Chromium Purification From Chromite Ore
A process for treating chromite-bearing ores to obtain useful mineral values especially platinum group metal therefrom wherein the ore is separated into magnetic and non-magnetic fractions; the non-magnetic fraction containing a substantial portion of the platinum group metals is concentrated and smelted to produce a metal layer containing platinum group metals; and the platinum group ...
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 …
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 …
Processing Chromite Ores - ccbvenezia.it
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.
A Process Mineralogical Evaluation of Chromite at …
The implications for processing chromite ore specifically at Nkomati would mean a target grind based on the chromite chemistry (with a focus on density) and that chromite liberation should not be the focal point during beneficiation. This is to say if the ore contains disseminated chromite, milling to a fine grind will most likely result in most of the chromite reporting to the tailings.

Chromite - Wikipedia
Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earths mantle.It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.
