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. Grade of iron ore is usually determined by the total Fe content in the ore. Run of mines ores after dry ...

Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth''s surface. In a surface mine, hard rock must be drilled and blasted, although some minerals are soft enough ...
