Extraction Metallurgy Process For Chromite Ore Mining

metallurgical processing of chromite ore

1. Introduction. Chromate production from chromite ore is an important basic metallurgical process but is usually a source of severe pollution. The traditional chromate production process used in China presently consists of three procedures: roasting of chromite ore, water leaching, and multi-stage evaporation and crystallization.

UNIT METALLURGY 1

The preliminary step in metallurgical process is removal of these impurities. This removal process is known as concentration of ore. It increases the concentration of the metal of interest or its compound in the ore. Several methods are available for this process and the choice of method will depend on the nature of the ore, type of impurity and
