chrome ore smelting

    Smelting chrome ore, Jan 01, 1976· Smelting chrome ore 855 Low carbon levels are more readily attained with a lumpy, coarse ore and when the slag has a MgO/Al 2 0 3 ratio of approximately unity Higher values of MgO/Al 2 0 3 are especially deleterious The presence of CaO also raises the carbon level The influence of these factors can be explained by their effect on the ,steps of processing chrome ore, steps of processing chrome ore Process first use hopper and vibration screen feeding stone chrome to preliminary crusher, then to fine crusher, then use belt to a hopper, underside the hopper have a feeder, feeder mm size to ball mill, ball mill working together with spiral classifier, then get mm size to shaking table, shaking table also have two stage, one for preliminary, one for fineSpinel Removal from PGM Smelting Furnaces, Others have chosen to accept that the chrome content places limits on ore blends, and adapt their mining and smelting plans accordingly This places constraints on mine life and furnace throughput, which in turn negatively affects profitability As low-chrome ore resources dwindle, the problem becomes more severe, and,WO2012057593A1, The invention relates to the production of ferroalloys, and specifically to methods for producing high-carbon ferrochrome in an ore-reducing electric furnace The problem to be solved is the involvement in the production process of materials which are unconditioned in size - chrome ore of less than 10 mm and a carbon-containing reducing agent with piece dimensions of less than 5 mmSamancor Chrome Mines, Dec 30, 2020· Samancor currently operates three flexible smelting systems with capacity in excess of 1Mt/y of ferrochrome at three sit The mines also feature six Submerged Arc Furnaces (SAF), a metal recovery plant, and a Pellet and Sintering Plant (PSP) Production In 2000, Samancor Chrome produced 37Mt of chromite and 106Mt of ferrochrome.
