Keywords: coal, beneficiation, ilmenite, magnetite Abstract— Coal beneficiation in South Africa is currently conducted mostly on a wet "float and sink" basis. This process is heavily water intensive and also potentially polluting. Dry beneficiation alternatives are being sought. The alternative of dry dense medium beneficiation using a ...Web

The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.Web

Global consumption of magnetite in non-metallurgical uses is not precisely known because magnetite production is commonly reported with other iron oxides such as hematite. In Australia, the major commercial application for magnetite is in the dense-medium washing process used in most coal preparation plants (Doral Resources NL 1990).Web
