Chrome Ore Beneficiation Process | Chromite …
3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite. Besides, the stone size is fine, so there is no need for grinding, the …

Chrome Ores on Ferrochrome Smelting
of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity. The electric energy consumption is highly related to the SiO 2 content of chrome ores. The lowest electric consumption of 3.31 MWh/t is required when the SiO 2 % of chrome ores is 6%. Considering the fact that the other contents do not change much in the ...
Chromite: The only mineral ore of chromium metal
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.
Chromium processing | Britannica
Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used. (Ores high in alumina are preferred for …

The control of a milling operation is a problem in imponderables: from the moment that the ore drops into the mill scoop the process becomes continuous, and continuity ceases only when the products finally come to rest at the concentrate bins and on the tailing dams. Material in process often cannot be weighed without a disturbance of continuity; consequently, mill control must depend upon the ...
