  • Case Study: Chromite mining and processing

    Chromium mining and processing In nature, chromium is found as chromite ore, composed of elemental iron, oxygen and chromium (FeOCr 2 O 3) 1,2 heavily in about a 700 m vicinity around the Countries with commercially significant chromite mines include Russia, South Africa, Zimbabwe, Turkey, the Philippines and India2 Chromite ore is initiallyThe Mining of Chrome in South Africa This report focuses on the chrome ore mining sector in South Africa The country holds 72% of global chromite resources, which includes more than 41% of the world’s reserves, and during 2014 the industry produced 15Mt of chromiteMining of Chrome :: South AfricaSouth Africa has a mature chrome value chain, the socioeconomic impact of which includes approximately 200,000 jobs and approximately R42 billion in GDP per annum However, the South African ferrochrome industry is under pressureChrome Mining in South Africa ProjectsIQ

  • Effect of South Africa Chrome Ores on Ferrochrome Production

    Chrome ores produced in South Africa are mainly from the mines that operate in the Bushveld Igneous Complex The Bushveld Complex contains a series of overlapping funnel shaped intrusions oriented from Doornvlei of North West Province to Steelpoort of Mpumalanga Province, covering an area of 180, 000 km 2, see Fig 1The word mine production of chromite is about 26 Mt (2013) with South Africa (42%), Kazakhstan (15%) and India (15%) the major producers in addition recycling accounts for about 50% of consumption Australias only significant chromite deposit, Coobina, is a straitform deposits in the Pilbara region of Western Australia, with a possible resource of 15 Mt at 294% CrChromite Department for Energy and MiningSOUTH AFRICAN LOCALANDEXPORT SALESOFCHROMITE ORE Intheearly1960s,Union Carbide Corporation announced thedevelopment ofanewprocess (argonoxygendecarburization ortheAaD process)forthe production of stainless steel, which involved the simultaneous injection ofargon andoxygenintothe moltenchargeinarefiningvesselTheinjectionofargonChromiuminSouthAfrica SAIMM The Southern African
