Recovery Of Iron From Steel Furnace Slags

A process for recovering iron from preliminarily decopperized molten copper smelter slags having an initial composition which includes iron oxide, silica, and aluminum oxide as the major constituents. These constituents are initially present in the range of 40-70 percent FeO, 25-40 percent SiO 2 and 5-10 percent Al 2 O 3 . The slag is maintained in a molten state and a solid reductant is mixed ...
