Magnetic Separation Process

Product Introduction

High intensity magnetic separation 

Limonite ore after classifier passes to high intensity magnetic separator. High iron content (+47.69%) limonite ore is moved to thickener and low iron content one to high intensity magnetic scavenger separation. the middlings are mixed with rough middlings for thickening process, while the rest ones are discharged as tailings.

First thickening, classification and grinding 

After first thickening, low iron content (-47.25%) limonite ore is moved to ball mill to be grinded into finer powder (90% < 0.067mm). The fine ore powder is mixed with middlings after first thickening for second thickening process. 

Second thickening 

The second thickening is conducted for further upgrading of limonite iron ore. The product with iron content lower than 40.08% returns to scavenging, and the one higher than 49.04% passes to reverse flotation.
