Hematite Separation Process

Hematite Separation Process . Process Introduction. The early hematite beneficiation is mainly gravity separation with machines of jigger, centrifugal separator, spiral chute, spiral washer, shaking table can be involved and later floatation separation has been used in the hematite iron ore upgrading with floatation separator and magnetic separator involved.

Hematite Roasting Beneficiation Process

The oolitic hematite with a lower iron content and a higher phosphorus content will be a potential source of raw iron ore for the Chinese iron and steel industry. The magnetization reducing roasted and magnetic separation is a practical beneficiation process. The results show that the iron content in the concentrate can be increased to 57.63% from 45.95%, the iron recovery up to …
