The South African platinum industry has advanced into an era of predominantly mining and processing Upper Group Two (UG-2) ore to extract Platinum Group Metals (PGMs). Flotation concentrates derived from processing UG-2 ore are typically characterized by high chrome contents (>3 wt.%) which are not amenable to conventional PGM smelters. The net effect of …Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.

Chromite ore is one of Turkey's major income sources in primary mineral exports. Ferrochrome production of Turkey was different between 2007 and 2011, at 69.73–60.00 metric tons. The demand for chemical-type ores has also increased with the operation of sodium bichromite-producing factories.Mar 02, 2016 0183 32 HYDROMETALLURGY METHOD FOR NICKEL OXIDE ORE European Patent Application EP2990495 Kind Code, When the step A of the invention is adopted, particles containing chromite in the ore slurry that is produced in the ore processing step are separated and recovered, so that abrasion of facilities such as piping and pumps at the ....

Because of the acute toxicity of Cr(VI)-bearing substances, the pollution problem caused by chromite process residue has become a worldwide concern. In the view of relevant studies, the technologies based on the alkali treatment cannot fundamentally resolve the pollution problem, because the oxidation of Cr(III) to Cr(VI) is unavoidable during chromite decomposition. In …Mar 02, 2016 0183 32 The hydrometallurgical process for nickel oxide ore according to claim 1 or 2, wherein the recovery process of the step A includes subjecting the ore slurry to cyclone classification, reducing fine iron hydroxide particles, and then recovering chromite particles in the ore slurry from the ore slurry as a concentrate of ...

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...Chromium (Cr) is the first element of Group 6 (the sixth column) of the Periodic Table, a transition metal with atomic number 24, an atomic weight of 51,996 and density of 7,19 grams per cubic centimeter. It is a hard, lustrous, steel-gray metal, whose multicolored compounds – like emerald and the above mentioned ruby – earned its name ...
