Primary smelting processes the mine ore and concentrates, and secondary smelting processes recover the scraps. 4. History of Smelting. The 14th Century is when smelting first began to be practiced in Europe. At that time, the blast furnace was introduced, which used greater air volumes, and layered the iron ore with charcoal, …
Kenya lacks a smelting plant so the company exports crushed stone containing iron ore for smelting and manufacture into steel products. What you need to know: General Nice Development has agreed to finance feasibility study after courting local mining company for joint venture deal
Blast Furnace – Basic Oxygen Furnace (BF-BOF): This is the dominant steel production route in the iron and steel industry, involving the reduction of iron ore to pig iron in the blast furnace. BF-BOF operation relies almost entirely on coal products, emitting ~70% of CO2 in the integrated plant (BF iron making).
