Sep 23, 2019· Concentration of Ore. The extraction of iron begins with concentration through calcination which is a process in a 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.
Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. Highgrade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.
At grain sizes below 100 µm, impurities such as silica and alumina are separated from the iron ore in a sequence of beneficiation steps, depending on the mineralogy of the iron ore. Removal of impurities from the iron ore is done prior to subsequent processing in pelletizing plants and directreduction plants.
