Previously the steel plant was selling its slag to a local cement producer, according to the New Indian Express newspaper. However, since moving to using online auctions to sell the by-product the prices have risen. In early 2017 the Union Tribal Affairs Minister Jual Oram alleged that the price of slag was being fixed. However the steel plant countered that it lacked railway infrastructure.

ArcelorMittal Ostrava’s slag recycling project receives acknowledgment by Czech government

19 October 2017

Czech Republic: A project by ArcelorMittal Ostrava substituting the primary raw materials for steelmaking with specially processed recycled slag has been ranked fourth in a government competition promoting the use of waste by-products as resources. The Ministry of Industry and Trade ran the competition that received 127 entries. Project manger Jitka Halamová attended the award ceremony on behalf of the steel producer.

“Since we've been using a special technology to sort the slag to end up a with higher iron content and a lower level of phosphorus, we have been able to reuse that slag in our operations in much higher amounts than before. Thanks to that, we are able to save iron ore, additives and fuel and, at the same time, we don’t accumulate large amounts of waste on our premises,” said Halamová.

The new technique mechanically processes the 0-8mm steel slag that contains 35 - 40% of iron. This has enabled ArcelorMittal Ostrava to increase the slag’s iron content to 54 - 57%, while keeping the phosphorus content low enough to reuse the enriched slag in the sintering process, replacing iron ore, additives and fuel in production. Using slag in this way increases the sustainability of the business’ operations and offers economic benefits. In 2016 ArcelorMittal Ostrava recycled on average 1900t/month of enriched slag and in the process saved a total of over US$0.87m.
