Experimental Study on Recovery of Super Pure Iron Concentrate from an Iron Concentrate in Sichuan
The iron grade of a iron concentrate in Sichuan is 64.56%, and the content of SiO2 and Al2O3 is 5.50% and 2.01% respectively. Material composition research shows that iron minerals are mainly in the form of magnetic iron. The process of stage grinding and magnetic separation which added dispersant H...

| Summary: | The iron grade of a iron concentrate in Sichuan is 64.56%, and the content of SiO2 and Al2O3 is 5.50% and 2.01% respectively. Material composition research shows that iron minerals are mainly in the form of magnetic iron. The process of stage grinding and magnetic separation which added dispersant H01 in regrinding is carried out to increase iron grade and reduce silicon content. Finally, the super iron concentrate with iron grade 72.11%, SiO2 content 0.20%, Al2O3 content 0.16%, acid insoluble content 0.28%, and the iron recovery is 92.72%. |
