The slag processor must also be aware of the general aggregate requirements of the end user. The processing of steel slags for metals recovery is not only important to remove excess steel at the market source for reuse at the steel plant, but is also important to facilitate the use of the nonmetallic steel slag as construction aggregate.

The processing process is: after the steel slag is coarsely crushed, it is crushed, screened and magnetically separated from the magnetic materials and non-magnetic materials. The metal content of magnetic materials is 50~60%, and these magnetic materials are sent to the selection process, i.e. grinding, screening and magnetic separation, so ...

BOS Slag. Process. When molten iron (referred to as "hot metal") from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed.
