A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with disseminated chromite), PCMZ_HG (high-grade Ni-Cu sulphide silicate ore ...
South African chromite ores and concentrates are blended to obtain a Cr/Fe ratio that is high enough to produce ‘charge chrome’, a special grade of high-carbon ferrochrome (HCFeCr). Charge chrome contains approximately 50–53% Cr, 6–8% C, 4–6% Si, and the balance Fe, with minor impurities such as S and P (Gasik, 2013). Not all ferrochrome in South Africa is produced via the

22-01-2021 With low electricity prices, South Africa has been able to expand chromite and ferrochrome production more or less continuously since the AOD process was developed in the 1960s to use ferrochrome smelted from lower-grade
Council for Mineral Technology, 200 Malibongwe Drive, Randburg, South Africa; [email protected]: [email protected] ABSTRACT Ferrochrome alloy is predominantly produced in AC submerged-arc furnaces where the electrodes are buried in the burden of lumpy materials comprised of chromite ores or pellets, reductants and fluxes.
Other important sources of chromite include Zimbabwe (with 12% of the world’s reserves), Kazakhstan (4%), Finland (2%), India (1%) and smaller amounts in Turkey and elsewhere. World production of chrome ore totals about 25 million tonnes per annum and is dominated by South Africa (41%), followed by India (16%), Kazakhstan (15%), Turkey (8%), and Oman (3.5%).

SOUTH AFRICAN PLATINUM-GROUP METAL ORES South Africa has the greatest concentration of primary PGM producing companies (14,15), each of which has their own approach to smelting, governed to a large extent by the type of ore that they process. The currently exploitable South African reserves of platinum-group metals are
South Africa’s troubled chromite industry appeared to have been temporarily halted by the decision announced by President Cyril Ramaphosa on Monday March 23 to impose a stoppage on the operations of the country’s mining sector.
cascade configuration with final concentrate being pulled from the re-cleaner cells. This “mill-float” configuration is commonly termed MF1 in South Africa. The primary grind was coarse limiting the risk of chrome entrainment into the final concentrate, but also limiting PGM recovery due to its inherent tendency not to recover more finely
