Slag recovery - SlideShare

 · Chromium recovery from ferrochrome slag can reach high values of 90–99 per cent within a reasonable time. Most of the chromium left in high carbon ferrochrome slag was found to exist as undissolved chromite. Eric and Akyuzlu (1990)19 investigated the slag/metal equilibrium in FeCr production conditions.
