Beneficiation of Iron Ores – IspatGuru

Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 70 % iron hematite or Fe3O4 72 % iron. magnetite . Ores are normally associated with unwanted gangue material.

Low grade Iron Ore Beneficiation and the Process of Jigging – IspatGuru

Since the iron ores consist of several compositions mineralogies shapes and sizes so there is no ‘one size fits all’ approach to the beneficiation of iron ore. Most of the ‘run-of-mine’ ROM iron ore contain a large percentage of other materials which need to be removed through the process of beneficiation before the ore attains the specifi ions needed for its use.
