THE PROBLEM WITH CHROMITE PROCESSINGTHE CHROMITE EXTRACTION FLOWSHEETCHROMITE PROCESS SUMMARYExperience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be removed after stage crushing and grinding to prevent further reduction of the chrome and consequentChat Online

Chromite The only mineral ore of chromium metal Geology
Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium. chromite deposits that are large enough for mining are

Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs.
Chromium processing Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 176;C (3,375 176;F) and boils at 2,672 176;C (4,842 176;F). In the pure state it is resistant to ordinary corrosion,
OVERVIEWPROPERTIESDISTRIBUTION OF DEPOSITSHEALTH EFFECTSAPPLICATIONSGALLERY OF CHROMITE MINERAL SPECIMENSChromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite. A substitution of the element aluminium can also occur, leading to hercynite. Chromite today is mined particularly to make stainless steel through the production of ferrochrome, which is an iron chromium alloy. Chromite grains are commoChat Online

Although the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not 100% 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).
Chromite . Chromite is an iron chromium oxide FeCr2O4. It is an oxide mineral belonging to the spinel The world's largest chromite mine is South Africa but it is also found in the The two main products of chromite refining are ferrochromium and metallic chromium; for those products the ore smelter process differs considerably.
