Experimental Study on Improving Grade of Talc Ore by Floatation

Abstract:

The experimental sample consists of talc, magnesite and a little quartz, the grade of talc is 80%. By the floatation flowsheet of rougher and two times cleaner, and middling after regrinding return to rougher, the high grade talc concentrate can be obtained. The concentrate contains talc 95.67% (SiO₂ 61.68%). Talc recovery rate is 89.43%. By this way, the output of high class talc product is increased and talc resources are exploited very well.
