Chromium processing Britannica

The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F). This creates a calcine containing sodium chromate, which is leached from the insoluble gangue and then reduced and precipitated as Cr 2 O 3.

Chromite Wikipedia

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds. It can be represented by the 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 (MgCr2O4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl2O4). Chromite today is mined particularly to make stainless steel through the production of ferroc

Chromite: The only mineral ore of chromium metal

Identification and Description of Mineral Processing

Chromite ore is prepared for processing using several methods, depending on the ore source and the end use requirements. Course clean ore is hand sorted, while fine clean ore is gravity separated. Lumpy ore mixed with host rock may require heavy-media separation. If the chromite mineral occurs in fine grains intermixed with host rock, crushing,

Extraction of Chromium from Chromite Ore

Jul 22, 2017 Chromite Ore Processing Low-grade ore obtained from an open cut trench at a chromite deposit near Auburn, Calif., was treated in the laboratory using gravity-magnetic separation and flotation beneficiation techniques. Flotation using known methods, however, gave very poor results and will not be discussed further in this report.
