1. Richer the ore, i.e. greater the iron content, the more economical the blast furnace smelting. 2. Low alumina/silica ratio is desirable. 3. Higher reducibility of iron bearing materials is desirable, this helps in decreasing the coke rate. 4. For coke, the prime objective is to maximize the carbon and thereby minimize the ash content. 5.
Grinding is continuous and fully integrated with subsequent flotation operations. SAG or AG mills. The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.
