Chromite an overview ScienceDirect Topics

Mining of chromite is carried out by open-pit and underground mining. Whereas open-pit mining is generally applied to podiform deposits, underground mining is applied to stratiform deposits. Chromite ore is mined in over 20 countries, but about 80% of production originates from four countries: South Africa, India, Kazakhstan, and Turkey

Chomite ore processing plants, CDE Global

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.
