The smelting of copper and lead in nonferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as ironsilicatebased slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component .
Beneficiation of Iron Ores Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite).
