NIOSHTIC, Rougher flotation of ore containing abundant olivine upgraded the chromite from 23.4 to 29.6 percent cr2o3 at a recovery of 89.4 percent. The technique was also applied to chromite gravity concentrates to further upgrade chromite and to reject silicates.Chromium Ore, Ferrochromium is manufactured by the reduction of the ore. In 2007, the world production of chromite was 20 million tons (U.S. Geological Survey 2008). The world resources of chromite are greater than 12 billion tons, and this is, according to the U.S. Geologicaldolomite ores separation from chromite ores by flotation, dolomite ores separation from chromite ores by froth flotation chrome ore dressing process in nigeriamovie.
