Mar 27, 2019· Steelmaking slag contains considerable amount of manganese (Mn) and phosphorus (P), and recycling them is an important issue. Since Mn is an alloy added to enhance the steel quality, while P is a harmful impurity in the steel product, they need to be separated for recycling. We have already found the possibility of separating Mn and P from steelmaking slag by selectively reducing
India too is one of the major producers of manganese ore . Click here to see .manganese.rockfert . Uses: Manganese is indispensable to iron and steel production.
