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.

Gold mines in Odisha at 18 lo ions spread across 8 Gold mines have been discovered in Odisha, which has a vast reservoir of mineral wealth like iron ore, bauxite and coal, during a survey by Geological Survey of India GSI and the state geology department.
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
