Incinerator Bottom Ash Metal Recovery by Sepro

Raw bottom ash is fed into a wet operated jig or wet screen classifier, which separates the fines fraction (-2mm) as a slurry. The fine bottom ash fraction, containing most of the precious metals, is then transferred into the FSTP. First, the slurry is processed through low-intensity magnetic separation to remove fine iron.

Steel Slag - an overview ScienceDirect Topics

In the primary process, crude steel is produced in two ways. In the first method, the iron is produced from ore in the BF, thus, generating BF slag (BFS). BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry.
