The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.

Roasting conditions for the best conversion of goethite to synthetic magnetite were a reduction temperature of 600 °C for 20 min in a gas mixture of 40:60 CO/CO 2. A higher reducing temperature of 1000 °C, although achieving greater conversion to magnetite, resulted in over-reduction and the generation of wüstite, fayalite and Fe-rich …

Pace will be responsible for the funding of all necessary capital equipment and the establishment costs of a beneficiation plant, which will produce the DMS-grade magnetite. Estimated to involve an initial cost of R35m (£1.65m), the proposed plant will be located in Ironveld's Lapon mining area.

The Magnetite project in South Africa is strategically located in the picturesque Limpopo Province of South Africa. Its focal point is the Rhenosterkoppies Greenstone Belt (RGB), an ancient early Proterozoic crust that holds significant iron mineralisation, particularly magnetite. Although some historical regional-scale mapping exploration work ...
