South Africa s BIC chromite seams are relatively low grade with Cr/Fe ratios of typically or less Early producers exploited reserves with Cr/Fe 518 OCTOBER 2004 The Journal of The South African Institute of Mining and Metallurgy supply these processes Both these processes can use UG2 as part of their ore feed to the pelletizing
A variable that is often understated in literature relating to industrial chromite oxidation is the influence of the seam from where the chromite concentrates were sourced South African chromite ore typically from the Lower Group LG Middle Group MG and Upper Group UG seams Bachmann et al 2019 influences the elemental and
The LG6 Main seam or Magazine seam is generally considered the most economically viable for chrome Richardson and Aylmer 1993 This mine has a mining width near m including an internal 40 cm waste band The seam dips north at degrees comprising 30 cm of chromite 40 cm of pyroxenite and 110 cm of chromite
This report focuses on the mining of chrome ore also known as chromite in South Africa Chromite contains the elements chromium and iron and is the sole commercial source of chromium During 2014 the South African chrome mining sector produced 15 million tonnes Mt of chromite and exported 7Mt of the material worth US$ while employing

The Mooinooi Chromium Mine is located in the North West province of South Africa It was established as an underground mining operation and began production in 1978 The mine primarily utilizes underground workings with one known shaft for accessing the ore deposits The mining method employed at this operation is known as breast stoping
Chrome Mining Projects in South Africa While South Africa s mining industry returned to profitability in 2019 despite a number of challenges manganese iron ore and chrome are the only commodities that have seen real production growth over the last 15 years
NKOMATI SOUTH AFRICA Nkomati is located in the Mpumalanga Province South Africa 300 km east of Johannesburg It is the only South African company to produce nickel concentrate which also contains copper cobalt and PGMs Nkomati produces chrome concentrate as well MINING The Nkomati deposit has a substantial resource
South Africa accounts for roughly 45% of the global annual chromite ore production and for 40% of the current world s chromite reserves USGS 2018 These reserves are associated with the Bushveld Complex the largest layered mafic ultramafic intrusion worldwide which was emplaced into the supracrustal rocks of the Transvaal Supergroup
The Tharisa mine produces PGM and chromite concentrates Credit Tharisa The mine has an open pit life of 20 years and an additional 40 years through underground expansion Credit Tharisa The South African PGM mine is expected to hold probable open pit and underground reserves of grading /t 5PGE Au /t 3PGE Au
The studies highlight significant environmental impacts of chromite mining across regions like India Pakistan Vietnam and South Africa Furthermore Table 2 outlines different exposure routes such as inhalation ingestion and dermal contact for miners industrial workers farmers and nearby residents
Chromite from South Africa is known to be low grade brittle and prone to result in fine ore during processing For the mining of chromite followed by smelting to produce ferrochrome the electrical intensity is 3 5 times greater than the direct energy intensity In the study period there was no discernible net change in direct energy
In this review chromite originating from South Africa and processes used by the South African FeCr industry are mainly referred to as it is estimated that South Africa holds >70% of the global viable chromite ore reserves [9 10 14 15] More so in 2012 chromite originating from South Africa accounted for 41% of globally mined ore
The mine used the DMS plant to produce saleable small lumpy product from the mine s LG6 chromite ROM run of mine and dumps at a minimum grade of 38% but it was very inefficient Craig
According to the Mining Intelligence Database 25 South Africa is currently the world s largest producer of chromite platinum group metals PGMs manganese Mn vanadium and vermiculite and is the second largest producer Mining in South Africa has a legacy of various occupational diseases that contribute substantially to mortality and
South Africa was the leading chromite ore producer Global chromite ore mine production was estimated to have decreased slightly in 2023 compared with production in 2022 Production in South Africa the world s leading producer of chromite decreased by an estimated 6% compared with production in 2022
According to Africa Mining IQ South Africa currently the world s leading chromite producer and Zimbabwe have the potential to satisfy around 90% of the world s chromite needs In addition research company Nester claims that global chrome ore demand reached 41 million tons in 2021 with a CARG outlook upward of % by 2035
Backeberg notes that China cannot replace all South Africa s chromite supply such that even in the event of an export tariff South Africa would remain a key supply source although
