摘　　要：该类矿床中的金大部分为次显微金和显微金,而共生的硫(砷)化物黄铁矿和毒砂是其主要载金矿物, 并以机械混入物或微包体形式赋存其间.矿石的品位与载金矿物生成期、晶形、粒度及碎裂程度有关.The gold contained in this type of minerals is mostly microscopic or Sub-microscopic. The associated sulfides——pyrite and arsenopyrite are the main gold loaded minerals, in which, the gold occurs in the form of mechanical mixture and microinclu-sion. The gold grade is related to the mineralization period, crystal form, grain size and cracking degree of gold loaded minerals.
