Chromite Ore Separation

Chrome Ore Beneficiation Process Chromite Processing

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.

Chromite Ore an overview ScienceDirect Topics

Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

Chromite Wikipedia

Chromite, when presented as an ore, or in massive form, forms as fine granular aggregates. The structure of the ore can be seen as platy, with breakages along planes of weakness. Chromite can also be presented in a thin section. The grains seen in thin sections are disseminated with crystals that are euhedral to subhedral.

A discussion of magnetic separation techniques for

In some cases, chromite concentrates can be produced by wet gravity concentration alone. In other chromite beneficiation processes, magnetic separation by RED is an essential polishing step. Figure 3 shows a typical flowsheet for upgrading chromite where gravity concentration is followed by dry magnetic separation. Case studies

Chromite Wikipedia

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earth's 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.
