Extraction of Iron Concentration of Ore - An Overview

2019-09-23  Concentration of Ore The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc. These impurities are known as gangue which is commercially useless so we must separate it from ...
