recycling electric slag:

Slag recycling - recovery

The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag
