Experimental Research on New Ore Dressing Methods for the Unworkable nated Gold Ores from Baishan Area
【摘要】 研究分析对比了不同类型难选金矿石的特点,采用复合处理剂湿法预处理-提金新方法使吉林白山地区微细浸染型难选金矿石选金回收率由27%~57%提高到92%以上。
【Abstract】 A large number of gold deposits in the Baishan area belong to the Carlin type and most of the gold ores from these gold deposits are fine disseminated ones and are high in As,C, Fe ,Si ,Cu and Co. Thus most of these ores are reluctant to ordinary ore dressing processes ,for instance,all - mud hydrite generation, floating, biochemical methods and roasting under high temperature. This paper introduces a new pre -processing method using treating compounds and related gold leaching procedure. By this way, the recovery ratio of the unworkable fine disseminated ores from the studied area would increase from 27% ~57% up to the present 92%.
