The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc.

How is iron extracted from its ore? It's a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top.

It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore; Since most minerals are not pure metals, further separation methods are required. Most minerals are chemical compounds that contain metals and other elements.
