中文摘要:
      辽宁海城滑石矿主要成分为滑石和菱镁矿,另有少量石英等。对手选尾矿试验采用粗磨粗选、二 次精选、中矿再磨返粗选的流程,可获得精矿品位滑石含量为95.67%(SiO2含量为61.68%)的高品位精矿粉, 滑石回收率为89.43%。对该手选尾矿进行综合回收利用,不仅提高了优质滑石产品的产量,同时使滑石资源 得到充分利用。
英文摘要:
      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.
