河南省金矿山尾矿非金属矿物资源化潜力分析

Analysis Resource Potential of Non-metallic Minerals of Gold Mine Tailings in Henan Province

通过测试河南省代表性金矿山尾矿的矿物组成和化学成分,研究分析了金尾矿非金属矿物的资源潜力。研究表明:近一半尾矿库尾矿中石英平均含量超过50%,可考虑回收石英精矿;约64%尾矿库的尾矿石英、长石含量之和超过60%,可考虑回收石英、长石用以作为制备瓷砖原料;尾矿的绢(白)云母平均含量范围2%~26%、平均值11.4%,可考虑对其回收利用绢(白)云母;约71%尾矿库的尾矿化学成分能够满足制砖工业原料组成要求。

The resource potential of non-metallic minerals in gold tailings was studied by testing the minerals and chemical composition of tailing samples from representative gold mine tailings ponds in Henan province.The results show that the average quartz content of tailings for recycling quartz concentrates exceeds 50% in nearly half of the ponds,and that the sum content of quartz and feldspar as raw materials for preparing ceramic tiles exceeds 50% in about 64% of the ponds,and that the average content of sericite(muscovite)which can be recycled in the tailings ranges from 2% to 6% and the average value is 11.4% ,and that the chemical composition of tailing in about 71% ponds meet the requirements of raw material in the brick industry.
