Experimental Study on Beneficiation for Talc in Haicheng Liaoning

In addition to a small amount of quartz, the main composition of the talc ore in Haicheng Liaoning is talc and magnesite. When the flowsheet of rough grinding and flotation, secondary cleaning and middlings regrinding to return to roughing was adopted for the hand tailings,the high-grade concentrate was obtained with the content of talc as 95.67%(the content of SiO2 as 61.68%)and the the recovery of talc as 89.43%.By comprehensive recovery of the hand tailings, not only was the yield of the talc improved, but also the talc resource was made full use.
