Get PriceChrome ore mining process xinhai process introduction chrome ore deposits are mined by both underground and surface techniques.Most chrome ore must be processed by the chrome ore processing plants.The mainly chrome ore beneficiation method is gravity separation.So the mainly used chrome ore concentrating equipments are ore washbox sometimes it is called jigger, concentrating.
What Can I Do For You?
The chrome spinel contains ore which is relatively high in iron or densely symbiotic with magnetite.In the concentrate obtained after ore dressing, the chrome grade and the ferrochrome ratio are both low, which can be considered as an ingredient for the production of ferrochrome by fire, or hydrometallurgical processing.For example, sodium dichromate method, chromium hydroxide method.
