SEVERSTAL RESOURCES performance in Q2

In Q2 2017 coking coal concentrate sales volumes from Vorkutaugol increased 16% driven by growth in production volumes following the scheduled long-wall repositioning at the Vorkutinskaya and Komsomolskaya mines in Q1. Following the sealing-off of the Severnaya mine, the Company expects to begin extraction of the Severnaya mine resources via the adjacent Komsomolskaya mine in 2020.

Iron ore concentrate sales volumes surged 54% QoQ to 1.24 million tonnes (Q1 2017: 0.80 million tonnes). Iron ore concentrate sales improvement in Q2 reflects seasonal dynamics and a planned production increase.

Iron ore pellet sales improved 12% and totaled 2.88 million tonnes (Q1 2017: 2.58 million tonnes). Iron ore pellet sales volumes were impacted by stock reduction.

Reflecting the above mentioned QoQ increase in volumes, revenue from the Resources division continued to grow, supported by relatively stable average selling prices. Revenue increased 11.1% QoQ, to USD 471 million (Q1 2017: USD 424 million) and EBITDA increased accordingly 11.2% to USD 238 million (Q1 2017: USD 214 million). In Q2 2017 Severstal maintained record margins at its Resources division, of 50.5%.

Given the fixed cost nature of the mining business, higher processing volumes at Vorkutaugol after the long-wall repositioning in Q1 reduced total cash costs (TCC) to USD 78 per tonne (Q1 2017: USD 83 per tonne). At the same time, increased sales volumes reduced TCC at Karelsky Okatysh USD 2 per tonne to USD 26 per tonne (Q1 2017: USD 28 per tonne). TCC at Olcon were down USD 6 per tonne at USD 28 per tonne (Q1 2017: USD 34 per tonne) partly reflecting a seasonal uptick in sales volumes.

Autonomous trains now driving 20% of pit to port kilometres in Australia – Rio Tinto

Computing.co.uk reported that mining giant Rio Tinto claims that 20% of its pit-to-port train movements in its iron ore mining network in Western Australia are now done by autonomous trains. The technology is being use for one-fifth of the kilometres piloted by the trains, with drivers standing by to take over in event of an incident and to drive the train in more complex environments.

The autonomous train project is being used in the company's network of 15 iron ore mines in Pilbara, a province of Western Australia, in a railway network of 1,700km.

The company in a statement released this week said that "The automation of the Pilbara train system [called Autohaul] is continuing to progress well, with around 20 per cent of all train kilometres now completed in autonomous mode, but with drivers on-board managing the remaining safety and reliability systems.”

It added that "Improvements to system performance continue and the project is on schedule to be completed by the end of 2018.”

It's not the company's first automation project. Indeed, Rio Tinto has arguably been a bigger pioneer of self-driving technology than Google, Volvo or any of the other names more commonly associated with autonomous vehicle technology.

And in 2015, it opened the world's first automated mine, which also included self-driving haulage trucks.

The company claims that "[Rio Tinto's] Yandicoogina, Hope Downs 4 and Nammuldi mines are the first in the world to move all of their iron ore using fully automated, driverless haulage trucks.”

It continued that "Rio Tinto first introduced the Autonomous Haulage System (AHS) at its iron ore operations eight years ago as part of its 'Mine of the Future' programme and is now the world's largest owner and operator of autonomous trucks. The group has 71 AHS trucks across three Pilbara iron ore mines, moving about 20 per cent of the operations' material."

In addition to autonomous trucks, the company also operates seven "fully autonomous drill systems" to drill production blast holes, and also made use of drones to, for example, measure stock pile long before drones started to be adopted elsewhere in industry.

Unscientific mining in Odisha result in massive deforestation

THE ASIAN AGE reported that unscientific mining of iron ore, bauxite and chromite in Odisha’s mineral rich districts such as Keonjhar, Sundargarh, Jajpur, Rayagada, Koraput and Angul districts have resulted in massive deforestation and air and water pollution.

Water sources, originating from forests, are increasingly getting polluted. Valuable topsoils and ore fines are being lost in the waste overburden. According to scientists, there is no proper mine closure practice in Odisha, due to which the mining projects are fast turning to be hazardous sites for locals.

Worse still, unplanned mining is limiting the opportunity for rehabilitation of people. Scientists, pleading for the maximum use of modern technology in mining, have stressed on post-mining land use development.

Country’s noted scientist and former director general for Council of Scientific and Industrial Research, Mr Prafulla Kumar Jena said that “Due to unscientific mining and mineral processing, a lot of water is consumed. Most water resources in the mining areas and the downstream get polluted with mineral wastes, including mineral beneficiation tailings and slimes. The dusty atmosphere and polluted water cause a lot of unhygienic conditions for the workers and the people living in the region.”

He added that “Further, mine closure program is seldom planned or implemented, leaving the mine area devastated and unproductive once mining is complete.”

According to Mr PK Dhal, an eminent researcher on water resources, rivers like Baitarani, Brahmani, Kharasrota, Tel and Koel flowing the Odisha’s mining belts have been contaminated beyond the tolerable limit, and they need urgent interventions from governments.

Mr Dhal said that “Besides, presence of huge volume of dust particles in the air, and soil pollution by the mining waste have rendered the mining belts inhospitable and uninhabitable. Locals are suffering from asthma, heart disease, strokes, chronic obstructive pulmonary disease and lung cancer. Children are suffering from acute lower respiratory infections, adding, hundreds of precious lives have been lost due to such diseases in the past two decades.”

In mid 1980s, Institute of Minerals and Metals Technology at the Council of Scientific and Industrial Research implemented a project named Mines, Minerals and Habitat in a chromite mine at Sukinda, Odisha belonging to Odisha Mining Corporation for environment friendly-scientific mining with integrated mine area development.

After its successful demonstration, the Maha program was taken up at a limestone mine at Lambidhar, Mussorie, Uttarakhand, with similar success. The programme was appreciated by experts and also then Prime Minister Rajiv Gandhi.

Dr Jena said through proper planning and implementing modern practices, it will be possible to conserve and utilise the minerals and other resources to the fullest while increasing the productivity.

Vale - 2Q17 Production Report

Vale iron ore production achieved a record for a second quarter of 91.8 Mt in 2Q17, 5.8% higher than in 2Q16, mainly due to the ramp-up of S11D in the Northern System. The Northern System, which comprises the Carajas, Serra Leste and S11D mining areas, achieved a production record of 41.5 Mt in 2Q17, 13.7% higher than in 2Q16 as a result of the S11D ramp-up, which is advancing according to plan.

Blended volumes in Asia totaled 14.8 Mt in 2Q17, 9.8 Mt and 3.7 Mt higher than in 2Q15 and 2Q16, respectively, as a result of the ongoing strategy to bring more flexibility to the integrated supply chain by increasing offshore blending capacity, thus enabling rapid responses to changes in market conditions.

Iron ore production will be within the lower end of the 360-380 Mt guidance range for 2017, and in line with the ongoing strategy to maximize margins.

Nickel production reached 65,900 t in 2Q17, 7.7% lower than in 1Q17 and 16.1% lower than in 2Q16, mainly due to the rebuilding of furnace #2 in advance of the transition to a single furnace operation and the scheduled maintenance shutdown in Sudbury.

Copper production was 100,800 t in 2Q17, being 6.2% and 4.6% lower than in 1Q17 and 2Q16, respectively. The decrease was mainly due to lower production in Sudbury as a result of the scheduled maintenance shutdown at the surface plants and mines.

Production of copper in concentrate at Salobo reached a record for a second quarter of 46,000 t, 13.0% higher than in 2Q16, mainly due to higher feed grades and stronger plant performance in 2Q17.

We are revising our nickel production guidance to 295,000 t in 2017, reflecting weaker than planned production results at our operations in Thompson, New Caledonia and Indonesia. For both finished production from New Caledonia and Indonesia, there is a lag in the impact of the weaker site production as the material is processed to finished product at our Asian refineries. Our revised copper production guidance is 447,000 t in 2017, reflecting the impact of unplanned maintenance in the mines in Sudbury, lower third party copper ore deliveries and higher than planned grade variability in Salobo.

Coal production in Mozambique reached a quarterly record of 3.0 Mt in 2Q17, 24.8% and 101.8% higher than in 1Q17 and 2Q16, respectively, with two thirds of total production being of metallurgical coal. Logistics operations in Mozambique reached all-time records, with railed volume[2] reaching 3.1 Mt in 2Q17, 15% higher than in 1Q17.

Sishen production increased by 38% to 7.9 million tonne due to improved mining productivity as a result of fleet efficiencies and higher plant yields. Waste removal increased by 38% to 42.7 million tonne, compared to 31.1 million tonne in Q2 2016 (H1 2017: 76.6Mt). Sishen’s solid and consistent performance and ongoing improvements since the restructuring have resulted in guidance being revised. Sishen is expected to produce between 28-29 million tonne of iron ore in 2017 and 155-165 million tonne of waste.

Kolomela production increased to 3.5 million tonne, up 11% compared to Q2 2016, due to productivity improvements. Waste mined increased by 22% to 15.3 million tonne through ongoing improvements in operational efficiency. Kolomela is on track to meet full year production and waste guidance for 2017 of 13-14 million tonne and 50-55 million tonne respectively.

Export sales increased by 8% to 9.4 million tonne compared to Q2 2016. Total finished product stocks were 4.4 million tonne, compared to 3.5 million tonne at year end. Sales volumes were delayed to H2 due to unfavourable weather at Saldanha port. Full year sales guidance has been increased to 41-43 million tonne.

South Africa new mining charter wiped out ZAR 50 billion

The Citizen reported that the proposed 2017 Mining Charter has already wiped out ZAR 50 billion of the market value of shares in listed mining companies in South Africa and could destroy the industry altogether, the Chamber of Mines has contended in court papers.

The chamber’s urgent application to stop the implementation of the charter was yesterday removed from the court roll in the High Court in Pretoria for the filing of further affidavits.

This was after the chamber accepted an undertaking by Mineral Resources Minister Mosebenzi Zwane that his department would not implement the charter in any way pending judgment in the interdict application.

It is expected that the application will be heard in September.

The chamber’s senior executive of public affairs and transformation, Mr Tebello Chabana said in court papers its members were fully committed to the transformational objects of the Mineral and Petroleum Resources Act, but the Mining Charter would, if implemented, destroy the very industry whose survival was necessary to give effect to the objects of the Act.

He said that “The publication of the 2017 charter had, and continues to have, a disastrous effect upon the mining industry as a whole, as well as investors. “The shock induced in all role players within the mining industry has been so profound that an amount in excess of ZAR 50 billion was wiped off the market value of shares in listed mining companies.

He added that “The effect of the 2017 charter has indeed been so profound that Moody’s, one of the top three sovereign ratings agencies, characterised it as ‘credit negative’, implying that it may lead to a further cut in South Africa’s credit rating.”

China June iron ore output hits 20 month high - NBS

Reuters reported that China's iron ore output jumped in June to its highest level since October 2015. Data from the National Bureau of Statistics showed that the strongest sign yet that soaring prices have spurred miners in the world's top consumer of the steelmaking raw material to boost production. Its output rose 5% from a year ago to 124.7 million tonnes.

It said that refined copper production was up 12% from the same time last year to 768,000 tonnes, its highest in 18 months.

Evraz Q2 iron ore production update

Evraz announced that in Q2 2017, production of iron ore decreased by 9.2% quarter-on-quarter, mainly due to lower volumes of sinter amid capital repairs at EVRAZ ZSMK’s sintering machines no. 1 and no. 2. The reduced output of pellets was also partly caused by the accidental outage of EVRAZ KGOK’s indurating machine no. 2 in June.

In Q3 2017, sinter output is expected to decrease by roughly 2.5% quarter-on-quarter, mainly due to capital repairs of sintering machine no. 2 at EVRAZ KGOK in September. Following the accidental outage of EVRAZ KGOK’s indurating machine no. 2 in Q2 2017, output of pellets should increase by roughly 5% quarter-on-quarter in Q3 2017.

Four Iranian steel projects ready - Official

IRNA reported that four steel production projects using sponge iron technology through the Iranian method PERED were launched. Head of the MME, affiliated to Iranian Mines and Mining Industries Development and Renovation Organization, Mr Hassan Karbaschi told IRNA that the sponge iron production plant in Shadegan, Miyaneh, Baft and Neyriz are either half implemented or are operational. He added that “For the first time, the PERED sponge iron technology with a production capacity of 300,000 tons was exported to China.”

Iranian technology PERED for producing sponge iron is registered internationally in Germany, according to Karbaschi.

Noting that the current production capacity of sponge iron in Iran is 18 million tons, Karbaschi said steel projects are required for producing 55 million tons of iron and implementing the projects through the Iranian method can play a significant role in meeting the 2025 Vision Plan in connection with the steel sector.

Pipeline companies weary of new import taxes

The Street reported that pipeline companies and the US steel industry are facing off ahead of a report due from the Department of Commerce that could lead to limits on pipelines' ability to import steel, a proposition pipeline companies say could spell doom for upcoming projects and the steel industry believes will bolster the country's economy. The report follows a presidential memorandum signed January 24 ordering the department to sketch out a plan for maximizing the use of domestic materials in pipelines built in the United States and was due Sunday, July 23.

Trump has in the past promoted policies that favored both industries, speeding regulatory approval for major pipeline projects early in his presidency, and recently mulling import tariffs on steel that are expected to be announced in the coming weeks. Commerce Secretary Wilbur Ross is a former steel executive whose policy papers advising the Trump campaign cited unfair trade practices as a drag on American steel companies.

The pipeline decision pits the two industries in a zero-sum effort to win over the administration, while also putting into conflict the president's twin goals of supporting infrastructure development and promoting domestic manufacturing.

Pipeline companies have said that an import restriction could increase prices. A study funded by industry groups said a requirement to source American steel could drive up pipe costs 25%, an amount that could add USD 76 million to the construction costs of most pipelines and up to USD 300 million for mega-projects like the USD 3.8 billion Dakota Access Pipeline.

Outokumpu verrast niet na winstwaarschuwing

Kwartaalresultaten wel fors gestegen op jaarbasis.

(ABM FN-Dow Jones) De Finse producent van roestvast staal Outokumpu heeft in het tweede kwartaal meer winst gemaakt, maar zoals reeds gewaarschuwd wel minder dan aanvankelijk voorzien. Dit bleek dinsdag uit kwartaalcijfers van de de sectorgenoot van Aperam.

Bij een omzet van 1,7 miljard euro, ruim meer dan de 1,4 miljard euro een jaar eerder, behaalde Outokumpu een EBITDA van 209 miljoen euro. Aangepast was dit 199 miljoen euro.

Daarmee waren de cijfers in lijn met de recente winstwaarschuwing, waarin de fabrikant waarschuwde voor een aangepaste EBITDA van ongeveer 200 miljoen euro. Voor deze waarschuwing mikte Outokumpu nog op een iets lager bedrijfsresultaat dan in het eerste kwartaal van dit jaar, toen dit 294 miljoen euro was. In het tweede kwartaal van 2016 behaalde de onderneming een aangepast EBITDA van 66 miljoen euro.

De resultaten, zo liet Outokumpu al weten bij de winstwaarschuwing, stonden afgelopen kwartaal onder druk door een lagere productie van ferrochroom doordat onderhoud langer duurde dan voorzien. Ook ondervond de fabrikant de nadelige gevolgen van lagere grondstofprijzen.

De nettowinst van Outokumpu verbeterde op jaarbasis van een verlies van 20 miljoen euro naar een winst van 109 miljoen euro.

Het rendement op het ingezette kapitaal (ROCE) steeg van 6,2 naar 13,2 procent.

Outlook

Ondanks de eerdere winstwaarschuwing herhaalde Outokumpu te verwachten dat de onderliggende "gezonde" vraag naar roestvast staal zal aanhouden.

Voor het lopende derde kwartaal mikt Outokumpu op een "significant" lagere aangepaste EBITDA op kwartaalbasis.

Het aandeel Outokumpu daalde dinsdag 2,8 procent.

Mr Trump curbs on steel risk trade war - JISF

Bloomberg reported that there’s a risk of a global trade war should President Donald Trump decide to restrict imports of steel, according to Japan’s leading mills group, which warns any new US curbs on the metal may provoke a tit-for-tat response that could drag in other products. Concern would deepen about the potential spread of protectionism if Trump acts, Mr Kosei Shindo chairman of the Japan Iron and Steel Federation, told reporters in Tokyo on Monday that a trade fight beyond steel could happen if countries retaliated in other areas, such as farm products.

Mr Shindo said that “If other countries respond with products other than steel, that would be opening a Pandora’s box noting that the European Union has already said it will consider retaliation if the US takes action. We are concerned about the possibility that a chain of protectionism would happen.”

While Mr Shindo doesn’t see any problems for Japanese steel, in terms of US national-security issues, choking off supply would hurt customers there.

He said that “We export valued-added steel products that can be made only in Japan, referring to specialty grades. If such products disappear, we will put the trouble on customers in the US.”

Australia partially ends probe against Vietnamese galvanised steel

Viet Nam News reported that Australia’s Anti-Dumping Commission has partial rescission of its anti-dumping, anti-subsidy investigation on Vietnamese zinc-coated (galvanised) steel. The ADC, under Australia’s Department of Industry, Innovation and Science, has also been investigating zinc-coated steel imported from India and Malaysia. However, only the probe on Vi?t Nam’s steel has been terminated partially.

Viet Nam’s Ministry of Industry and Trade said the ADC concluded that Vietnamese galvanised steel producers and exporters received countervailable subsidies from the government during the investigation period, but the subsidies were at negligible level. Therefore, the ADC has decided to terminate the anti-subsidy probe on all Vietnamese galvanised steel producers and exporters.

The ADC will not recommend any subsidies for Viet Nam in its final report to the Minister for Industry, Innovation and Science.

Also, Australian investigators found that the dumping range of two of the three Vietnamese exporters was even lower than the minimal level. As a result, the ADC has terminated investigation into these two companies.

To arrive at the decision, the MoIT said, the ADC took into account complaints from the concerned parties, the statement of essential facts, comments relating to the SEF, and information it gathered from the investigation process.

Parties can seek a review of the decision by lodging an application with the Anti-Dumping Review Panel within 30 days of publication of the notice

Essar Steel argues against SBI’s insolvency petition before NCLT

Mint reported that Essar Steel Ltd’s lawyers on Monday raised technical objections to the insolvency petition filed by State Bank of India before the National Company Law Tribunal in Ahmedabad. Essar’s counsel Mihir Thakore said SBI’s petition was incomplete as it was not authorized by the bank’s chairman.

He quoted a section of the State Bank of India Act 1955 which deals with the power of the chairman. Mr Thakore argued that as per records submitted to the tribunal, the person who signed the application did not get authorization from the chairman. He also said there was no document showing the SBI board authorized the chairman to file such a petition. He called for a revised application to be filed.

Secondly, Essar lawyers also argued that the hearing should be done in two stages—one for admitting or dismissing the application and the second for appointing an interim resolution professional (IRP), if a petition is admitted. They argued that provisions of the insolvency and bankruptcy code give NCLT up to 14 days for appointing an IRP once a petition is admitted. They added that once an order is passed for admission of petition, the respondent should get a chance to approach a higher authority such as National Company Law Appellate Tribunal.

SAIL RSP bans plastic bags below 50 micron thickness in its markets

Indian Express reported that The Rourkela Steel Plant has banned sale of commodities in plastic bags below thickness of 50 microns in its market complexes in Rourkela. The steel plant has undertaken the measure by invoking the provisions of the Plastic Waste (Management and Handling) Rules, 2016 with a commitment for strict enforcement in its market complexes, a release from RSP said. Through a notice issued to all licensees and shopkeepers operating in the RSP market complexes, the town administration authorities of the steel plant have summarily banned the sale of commodities by them to customers in plastic carry bags or plastic sheets or multi-layered packaging below 50 microns in thickness, it said.

Any violation of the rules in question would attract structured and progressive penalties. It will be INR 4500 forthe first violation which will go up to INR 6000 and INR 8000 for the second and third violations. After violation for the third time, the licence would be liable for cancellation, it said.

RSP has also appealed to the general public to shun both the use of and demanding for such plastic bags which are not only a threat to the environment but also have a negative impact on Swachha Bharat Abhiyan, the release added.

Russian scientists develop porous, floating aluminium alloy

Aluminium Insider reported that researchers in Russia have announced the development of an unsinkable aluminium alloy by making the substance porus. St. Petersburg’s Peter the Great St. Petersburg Polytechnic University’s Laboratory of Light Materials and Structures developed the breakthrough material by introducing gas into the process of remelting while the aluminium alloy was in its liquid state. In addition to adding buoyancy, scientists say the process also improves the material’s stiffness, sound, and heat insulation properties.

Deputy head of the Laboratory of Light Materials and Structures SPbPU Oleg Panchenko explained that “A high porosity level can be used to decrease the density of structural elements, e.g. sheets. The density can be decreased even lower than the density of water. Resulting structural elements would be unsinkable. And its usage in shipbuilding will ensure unsinkability even with a leak in the hull.”

This new alloy also overcomes certain problems encountered with thinner materials with a thickness of 1 millimeter (0.04”) or less. Such materials often have sufficient strength for the tasks they are asked to carry out, but bending or joining them deforms and/or weakens the materials. With porous aluminium, thickness may be increased to allow for such manipulation without loss of strength or addition of weight.

This breakthrough represents the next step in porous materials, taking the baton from Japanese researchers who previously developed material that is entirely porous but without limiting the distribution of pores to either homogeneous or heterogeneous layouts. Researchers at SPbPU overcame this limitation by using solid material, allowing for double layers of the material that limits porosity to one side, enabling added strength for welding or other joining methods.

Founded in 1899 as the Saint Petersburg Polytechnic Institute, SPbPU is considered to be among the top research facilities in Russia and the CIS. It is widely recognized as an educational and research leader in industrial engineering and chemical engineering, among other fields.
