extraction of iron class 12, general principles and

May 15, 2020· Extraction of Iron. 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 bygravity separation processin which it is washed with water to remove clay, sand, etc. 2) Calcination
