A thermite reaction is a type of aluminothermic reaction in which aluminium metal is oxidized by the oxide of another metal, most commonly iron oxide. The name thermit is also used to refer to a mixture of two such chemicals. The products are aluminium oxide, free elemental iron, and a large amount of heat.

The major advantage would be elimination of the magnetic separation and froth flotation operations, which

Process Of Chromium Prodution From Chromite

The two main products of chromium ore refining are ferrochromium and metallic chromium. For those products the ore smelter process differs considerably. For the production of ferrochromium, the chromite ore FeCr 2 O 4 is reduced in large scale in electric arc furnace or in smaller smelters with either aluminium or silicon in an aluminothermic ...For the production of ferrochromium the chromite ore FeCr 2 O 4 is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process.Feb 20 2011nbsp018332Chromite FeCr2O4 is the most important commercial ore of chromium. One of the steps in the process used to extract chromium from the ore is the reaction of chromite with coke carbon to produce ferrochrome FeCr2. 2 Cs FeCr2O4s FeCr2s 2 CO2g What mole ratio would you use to convert from moles of chromite to moles of ferrochrome.A.
