Recovery of Chromite Values from Plant Tailings by Gravity

Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in table for the recovery of chromite values. Optimisation study was carried out for the process parameters of table using empirical models, developed from the experimental

Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr[VI]). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste COPR....

How Is Chromite Used? | Reference

Chromite, a mineral ore that is mined from crystallized magma, is used in the production of steel as a pigment and as a catalyst in many chemical reactions. It is also an important component of the leather tanning process. Chromite is also used to anodize aluminum for use in jet engines. Keep Learning.

Magnesiochromite, Magnetite. Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series....

Chromite: The mineral Chromite information and pictures

The Mineral chromite Chromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections.

Chromite and magnetite are ore minerals that form in this way. Liquid immiscibility : sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma....

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.

In this process, the chromite suspended in the molten (or sub-molten) alkaline medium is decomposed by oxidation, and then the chromium salt is prepared by separation, filtration, and purification steps. In relation to the liquid phase oxidation process of chromite in ...
