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 chrome ore beneficiation processes include gravity separation, flotation, magnetoelectric separation and chemical beneficiation, etcChrome Ore Beneficiation Process Chromite Processing Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict During wartime, the United States government supported domestic production with price supports and strategic stockpiling programsChromite mining The Oregon Encyclopedia

The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F) This creates a calcine containing sodium chromate, which is leached from the insoluble gangue and then reduced and precipitated as Cr 2 O 3Jan 01, 2016 Although the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not 100% efficient, so mining and smelting wastes including dust, wastewater, tailings, waste rock, and slag (produced during ferrochrome separation from the ore) still can contain different forms of Cr, including Cr(VI)Chromite ScienceDirectp0165 Although the intention of chromite mining is to re move chromite from the ore for the production of ferrochrome, the process is not 100% efficient, so mining and smelting was tes including (PDF) Chromite ResearchGate
