Because chromium is the most used metal and ranks first in the "strategic metals". Nowadays, countries with chromium ore resources or countries with lack of resources are stepping up the research on chromium ore dressing, and their separation methods are as follows;
1) Gravity separation: jig, shaking table , spiral chute, heavy medium cyclone, etc.
2) Magnetoelectric separation: high-strength magnetic separation and high-voltage electric separation.
3) Flotation and flocculation flotation.
4) Combined selection: gravity selection and electric selection.
5) Chemical beneficiation: treatment of very fine refractory chromium poor ore.
In the above chromium ore dressing methods, gravity separation is mainly used in production, and shaking table and jigging are often used. Sometimes the gravity concentrate is re selected by weak magnetic separation or strong magnetic separation to further improve the grade of chromium concentrate and chromium iron ratio.
