US: Vallejo Marine Terminal (VMT) has decided not to appeal against the Vallejo City Council’s decision in 2017 to deny it planning permission to build a marine terminal. VMT and Orcem Americas were planning to build a marine terminal and a slag cement grinding plant, according to the Vallejo Times Herald newspaper in Vallejo, California. Orcem Americas have not commented on the situation but the lack of an import terminal may make building a cement plant unviable, although the site does have rail and road links.

Indonesia: Fajar Harry Sampurno, the State-Owned Enterprises (SOE) Ministry's undersecretary for mining, strategic industries and media affairs, says that the Environment and Forestry Ministry will issue rules stating that mineral waste such as slags resulting from processing nickel and copper ores could be used as raw material for the production of bricks, asphalt, concrete and cement. Mineral waste including copper and nickel slags are currently categorised as hazardous and toxic waste (B3), requiring special handling, according to the Jakarta Post newspaper.

Harjanto, the Industry Ministry's metal, machinery, transportation equipment and electronic industries director general, said the volume of nickel slag, which at present totals 20Mt/yr, would increase ‘sharply’ within the next few years when new mineral smelters currently under construction start operating. The government expects the construction of 31 smelters to be completed by 2021. At the end of 2018 27 smelters were operating, of which 17 are nickel smelters.

Turkey: Erdemir Group has ordered new INBA slag granulations systems as part of an order for two new blast furnaces (BF) from Luxembourg’s Paul Wurth for its Ereğli and Iskenderun integrated steel plants. At both sites a new furnace will replace an older production unit. The new blast furnaces are scheduled for blow-in in March 2021 and May 2021 respectively. No value for the order has been disclosed.

At Ereğli Erdemir’s new BF2 will have a hearth diameter of 10m, 24 tuyeres and two tapholes. It will produce 5000t/day of hot metal from an inner volume of 2188m³. At Isdemir the new BF1 will be sized at 12.5m in the hearth and 3587m³ of inner volume; it will be fitted with 32 tuyeres and four tapholes and will produce 7900t/day, which further increases the hot metal capacity at this site.

Paul Wurth will execute both projects on an EP basis including the supply of technological key items and related supervision of erection and commissioning. The orders include basic engineering of the blast furnaces with profile, cooling and lining concepts as well as the design of the stockhouses, top gas cleaning plants, slag granulation plants and BF cooling units.

For both furnaces, Paul Wurth will supply Bell Less Top charging systems and bleeder valves, refractories for the hot blast mains and bustle pipes, tuyere stocks with tuyere phenomena detection system (TPDS), technological and critical items for the top gas cleaning plants (consisting of axial cyclones, annular gap scrubbers) as well as for in total three INBA slag granulations systems. Extensive sets of TMT probes and process recorders include, inter alia, 3D TopScanburden surface profile meters and SOMA acoustic top gas temperature measurement. Under the same contracts, TMT will also supply fully hydraulic taphole machinery for equipping all the six tapholes in total.

UAE: Emirates Steel has signed a deal with Finland’s Ecofer for slag management services for 10 years from 2020. Ecofer will process slag from Emirates Steel's Abu Dhabi plant and sell it to the construction industry, according to the Khaleej Times newspaper. The steel producer has been recycling its Electric Arc Furnace (EAF) slag product since 2014, producing roughly 2.8Mt of EAF slag in this period.

"As one of the largest integrated manufacturers of finished steel products in the region, we produce 0.8Mt/yr of slag and we are committed to finding ways to mitigate our impact on the environment,” said Saeed Ghumran Al Remeithi, the chief executive officer (CEO) of Emirates Steel.

Ecofer arranged an agreement with Egypt’s Ezz Steel earlier in 2019. The latest deal with Emirates Steel continues its intent to build strategic partnerships in the Middle East.

Europe: AcelorMittal has received approval from the European Commission (EC) for the sale of selected steelmaking assets to Liberty House Group. The divestment includes ArcelorMittal Ostrava in the Czech Republic, ArcelorMittal Galati in Romania, ArcelorMittal Skopje in North Macedonia, ArcelorMittal Piombin in Italy, ArcelorMittal Dudelange in Luxembourg and several finishing lines at ArcelorMittal Liège in Belgium. The assets are part of a divestment package that AcelorMittal agreed with the EC during its merger control investigation into its acquisition of Ilva. The transaction is expected to close before the end of the first half of 2019.
