Roasting a concentrate makes smelting more environmentally friendly; it also enables furnaces to accept any proportion of chromite, resulting in more efficient and cost-effective platinum production [9, 23].

Washington : Bureau of Mines, 1956 (OCoLC): Material Type: Document, Government publication, National government publication, Internet resource: Document Type: Internet Resource, Computer File: All Authors / Contributors:Chinese Chromite Smelting MillsAlthough the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not 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).Conventional Metallurgical Process Of Smelting Of Chromite ...chrome concentrate production process binq mining chrome ore beneficiation plantsmay 13 2013 of briquetted chrome ore fines in the production of ferrosilicon chrome and high carbon the conventional metallurgical process of smelting of chromite o...Improving the Quality of Ferruginous Chromite Concentrates ...The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.
