A fundamental problem in the genesis of all stratiform chromite deposits is how layers of massive to semimassive chromite that are commonly up to 1 m thick (, Bushveld [South Africa], Stillwater [Montana, USA]), less commonly up to 10 m thick (, Inyala and Railway Block [Zimbabwe], IpueiraMedrado [Brazil], Uitkomst [South Africa], Sukinda [India]), but in some .

Apr 24, 2020 · The process of chromite ore mining can be divided into 2 areas: 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens, and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.

Stratiform, Podiform, and Beach Sands. Small amounts of chromite are found in many types of rock. However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the ...
