Iran: The Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO) has released information about the Kahnuj titanium slag plant that was opened in November 2016. The unit has a production capacity of 70,000t/yr of titanium slag that will be used in the pigment industry, replacing foreign imports. Alongside this unit the 130,000t/yr Kahnuj titanium concentrate plant was also opened.

UK: Breedon has agreed to acquire the Sherburn Minerals Group for a total consideration of up to Euro18.4m, subject to completion adjustments. The acquisition will add Sherburn’s two terminals in northeast England and eastern Scotland, that are used to import cement and ground granulated blast-furnace slag (GGBS), to Breedon’s Hope cement plant.

Sherburn is an independent heavyside building materials business headquartered in County Durham, employing approximately 110 people. It operates four quarries and five ready-mixed concrete plants in County Durham, Northumberland, North Yorkshire and Cumbria. It also distributes cementitious products from two import terminals at Blyth near Newcastle and Dundee in eastern Scotland.

Following completion of the acquisition Paul Allison, Sherburn’s current Managing Director and a minority shareholder, will remain with the business as a consultant.

France: Ecocem France has ordered a Loesche type LM 46.2+2 CS mill for a slag cement grinding plant that it is building in Dunkirk. It follows a previous order by Ecocem of a LM 46.2+2 CS mill for the dry grinding of ground granulated blast furnace slag (GGBFS) at its plant at Fos-sur-Mer.

The LM 46.2+2 CS for the plant in Dunkirk is designed for the grinding of cement clinker and granulated blast furnace slag at a capacity of 105t/hr GGBFS. The gearbox will have a capacity of 3150kW.

All the mechanical equipment for the grinding plant starting from mill feed to the product discharge into the product silos is included in the Loesche scope of supply. The Loma heater type LF 28-L will be a full-inlined type designed to burn natural gas as well as blast furnace gas. The burner supplied by Loesche will be the MSBZ type, complete with fitting rack and local switch cabinet.

The lead-time for the main components of the mill and for the additional units included in the scope of supply is 6 to 13 months. The commissioning of the vertical roller mill is planned for the middle of 2017.

Ecocem’s grinding plant will be installed close to Arcelor steelworks for use of their granulated blast furnace slag. This LM 46.2+2 CS will be the seventh Loesche vertical roller mill installation for slag and cement grinding in France.

Russia: NLMK Group has completed hot-testing of its new crushing and screening unit for the processing of steelmaking slag at its Lipetsk plant. The project will double the amount of scrap, or ‘metal inclusions‘, extracted from waste and returned to the production process. The new unit will process 2.4Mt/yr of slag, replacing an obsolete unit, which processed 1.7Mt/yr of slag. Metal extraction efficiency at the new unit will be as high as 95%, which will minimise the consumption of iron ore and scrap in pig iron and steelmaking operations through replacement with recoverables. The project had an investment of US$7.2m.

“The new unit will process the entire volume of our steelmaking slag, which is about 2.2Mt/yr, as well as allowing us to eliminate the need to process slag via third parties. The unit will also help us to recycle previously accumulated waste. This Strategy 2017 project is our next step towards increasing the role of recycling in bringing down steelmaking costs and reducing our environmental footprint,” said Sergei Filatov, the managing director of Novolipetsk.

Recovering production waste is one of NLMK’s priorities as part of its operational efficiency improvement efforts. NLMK Group is currently building a new briquetting plant at the Lipetsk plant. Briquettes will be manufactured from a mix of iron ore concentrate and blast furnace slag formed in the process of wet blast furnace gas cleaning. The plant will recycle more than 350,000t/yr of blast furnace waste.
