Beneficiation of Iron Ores – IspatGuru

Apr 03, 2014  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). ... Chemical reagents used are mainly of three main groups namely (i) collectors/amines, (ii) frothers, and (iii ...
