intent of chromite mining

Even though the intent of chromite mining is always to take away the chromite from the ore for production of ferrochrome,the procedure is just not 100% efficient, so mining and smelting wastes like dust, wastewater, tailings, waste rock and slag (developed in the course of ferrochrome separation in the ore) can nevertheless include chromium (which includes Cr-VI).Other heavy metals and chemical compounds of concern may possibly also be within the wastes. As with other varieties of mining wastes,chromite mine wastes possess the potential to result in critical environmental contamination,as has occurred in areas around the world where these wastes happen to be inadequately managed.

chromite mining and ferrochrome production

Chromite ore is mined, crushed and processed to make chromite concentrate.To make ferrochrome, chromite concentrate is combined with a reductant (coke, coal, charcoal or quartzite) inside a high temperature submerged arc furnace or direct current arc furnace.Chromite ore mining and concentration produces overburden and waste rock, dust, tailings and tailings water. Ferrochrome production creates air pollution, dust, slag (waste produced in the course of ferrochrome separation from other ore components) and process water. These waste components have the possible to be contaminated with chromium along with other heavy metals and chemical substances of concern.

chromite mining process

ore extracted in the mine using a grade of 40% chromium oxide or greater is suitable for processing straight within the off-site ferrochorme production facility.Ore with reduce grade must be processed to in crease its chromit content.Ore that’s not appropriate to ship straight to the ferochrome procution facility will probably be processed in the mine web-site to create concentrate.The processing of chromite ore separates and concentrates the worthwhile chromit mineral.This includes mechanical processes and separation making use of gravity.The outcome is actually a concentrate suitable for refining,and “tailings”that have no financial worth.Tailings are the components left more than frome the ore processing facility immediately after the chromite has benn extracted from the ore.Tailing might be managed over the long-term in the mine web page within a tailings mnagement area.
