Description

Chromium ore is an indispensable mineral resource for the development of metallurgy, and chemical industries. It is mainly used for the production of stainless steel and various alloy steels and alloys in the metallurgical industry. It is also widely used in glass, ceramics, and refractory.

The main components of chromium ore include: Cr2O3, FeO, SiO2, MgO, Al2O3, P, S, etc.
