Capacity: 10-280TPH Application:More than 30 kinds of chromium ores in military, aviation, automobile, national defense, shipbuilding and other fields.
Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc. Sometimes it will also use weak magnetic separation or strong magnetic separation for re-separation, thus further improving the chromium concentrate grade and chromium-iron ratio. In addition, some mines will also use flotation and flocculation flotation methods.
For chromite beneficiation, there are many methods such as gravity separation, flotation and magnetic separation. Fote will give the final beneficiation method based on the ore analysis report and beneficiation test report, etc. The main process of commonly used gravity separation is:
1. The chrome ore with qualified fineness after crushing and grinding will send to spiral classifier for cleaning and grading by relying on principle of different proportion of solid particles and the velocity of settling in liquids. Then being sent to jigger and shaking table.
2. Using spiral chute to separate fine fineness mineral powder.
3. After separated by spiral chute, the fine mineral powder will be sent to flotation machine or magnetic separator. The ore concentrate entering flotation machine will be dehydrated by thickener
4. The wet concentrate will be sent to rotary dryer for drying, thus getting the wet ore concentrates or returning to ball mill for re-grinding.
Fote designed a gravity separation process for one of our customers who has chromite mine with ore grade of more than 30%. His ore belongs to rich ore, but there also has poor chromium ore with different grade. Therefore, our company deeply studied the ore processing technology and selected the proper equipment for our customers. Under the grinding granularity of 200mesh in 60%, the customer finally obtained refined chrome ore with the grade of 39.9%. The chromium recovery rate is up to 64.56%.
