IntroductionMagnetite is recovered as a by-product of the copper operations. Since operations commenced in 1965, Magnetite has been separately stockpiled onsite.
Safety Data sheetMagnetite - material safety
ScopeThe Specifications cover the following two magnetite products:
- Dense media separation (DMS) - medium grade; and
- Iron ore (coarse grade)
ManufactureCurrent magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage. This results in the upgrading of magnetite to 66% Fe (greater than 95% magnetite). This upgraded magnetite is then subjected to elutriation, to generate medium and coarse grade products. The medium grade is the DMS product and the coarse grade is sold as a blend feed to iron- and steelmaking customers.

Product contactEnquiries from potential customers regarding DMS medium grade product should be directed as follows:
South African market:
Martin and Robson (M&R) Industrial Minerals have the domestic mandate to market and sell DMS medium grade magnetite product in the Witbank and Natal coalfield areas. M&R form part on the Sturrock and Robson Group and are contactable at email@example.com. Palabora sells directly to the Kumba Resources group who own the Grootegeluk and Tshikondeni coal mines.
Palabora has received numerous enquiries on the application of DMS medium grade product from overseas coal washeries.
