新疆某金矿工艺矿物学研究
|
摘要
采用化学分析、显微镜分析和MLA矿物自动定量检测技术,对新疆某金矿石进行工艺矿物学研究.结果表明,该矿石的主要有价元素为金、硫,可综合回收银.金主要以含银自然金和自然金形式存在,嵌布粒度极微细,均小于0.04mm.银主要以合金形式赋存于金粒中.黄铁矿的嵌布粒度较粗,多数大于0.04mm.可解离的自然金、包含于黄铁矿(含黄铜矿)中的金及包含于脉石矿物中的金分别约占59%,39%,2%,金的理论回收率约98%.
The process mineralogy of a gold ore from Xinjiang province is studied by chemical analysis,microscope,and MLA mineral automatic quantitative technology.The results indicate that the main valuable elements in the ore are gold and sulfur,silver could be comprehensively recovered.The Gold with very fine dissemination size(-0.04mm)mainly exists in the form of silver-bearing native gold and native gold,and the silver mainly exists in the gold grain with form of alloy.The dissemination size of pyrite is coarse,which is mostly above 0.04 mm.Dissociable natural gold,gold still contained in pyrite(containing chalcopyrite)and gold contained in gangue account for 59%,39% and 2%,respectively.The theoretical recovery rate of gold is 98% around from natural gold and pyrite dressing recovery.
