Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.Web
The two main iron ore producing companies in South Africa are Kumba Iron Ore, a subsidiary of Anglo American, and Assmang, which is a joint venture between African Rainbow Minerals and Assore.

Introduction. Sishen Mine is the largest iron ore mine in the Republic of South Africa. It is situated on the northern end of a range of hills, with 60 km of strike along the western limit of the Maremane Anticline or Maremane Dome, which contains lithologies of the Transvaal and Olifantshoek Supergroups (Fig. 1).The origin of iron mineralization …Web
Black Mountain Mining (BMM) comprises the Deeps and Swartberg Shafts, and the Gamsberg zinc mine and plant in South Africa's Northern Cape Province. The project has the potential to reduce BMM's cost of production by $30 – $500/t and therefore extend the life of the operations.Web
Our sorting equipment or mineral processing equipment, specially developed for mining applications, enables processes to be better controlled, and through ore sorting even ores that were previously not economically viable, can be efficiently and profitably processed. And our STEINERT technology is even effective in situations in which tailings ...Web
