Hematite Separation Process

Application

the separation process of hematite can be applied to hematite and impurity inlaid size and fine particle size, and a small amount of magnetite. The gangue minerals contain quartz and kaolinite with complex hematite.

Process introduction

Strong magnetic iron ore separation process
It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding. At present the fine grinding technology improves the concentrate grate from 61% to 67%.

Weak magnetic iron ore separation process
Weak magnetic mineral could use the strong magnetic mineral separation process after the magnetizing and roasting.

Fine Grinding
In two stages grinding, stages separation, single weak magnetic flow, fine grinding means adding fine screen regrinding process to separate fine minerals timely and reduce the over-grinding. It improves the capacity of ball mill and concentrate grade by 2%.
