metallurgical processing of chromite ore

Green metallurgical processing of chromite - ScienceDirect

Aug 01, 2006  1.. IntroductionChromate 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.
