machinery equipment and energy used in extraction of iron ore

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.
