Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.

After the air is brought up through the water, bubbles form that float the waterrepellent copper particles to the surface of the water. This separates out the froth which has 30% copper, 27% iron, and 33% sulfur. The flotation process gets rid of impurities in the ore, where there may also be lead and other vital metals in our society such as ...
