采用光薄片鉴定、人工重砂分析、化学成分分析、电子探针波谱分析等技术方法，查明了响水洞金矿床矿石类型以石英脉型矿石为主，其中黄铁矿为金的主要载体矿物，黄铜矿、磁黄铁矿为次要载体矿物，石英为主要的脉石矿物，绿泥石和方解石等为次要脉石矿物。矿石的构造类型主要为脉状—细脉状、浸染状、块状、角砾状等。金矿物主要以银金矿形式存在，呈独立矿物形态，粒度主要集中于0.01~0.075 mm。矿石的结构构造有利于各矿物的单体解离，在细磨条件下大部分金矿物解离呈单体金，综合回收率90.84%以上，矿石的性质总体对选矿有利。
Technical methods of thin sections determination,artificial heavy concentrate analysis,chemical compo-sition analysis and electronic probe spectrum analysis find that the principal gold ore type in Xiangshuidong Gold De-posit is quartz vein. The gold-bearing minerals are dominated by pyrite followed by chalcopyrite and pyrrhotite. Gangue minerals are mainly quartz,and then chlorite and calcite. Ores are in the form of veinlet structures,disseminated struc-tures,massive structures and brecciated structures. Gold minerals are present in an independent mineral form of elec-trum with sizes ranging generally from 0. 010 mm to 0. 075 mm. Ore textures and structures facilitate individual miner-al separation,and most of the gold minerals are likely disintegrated to native gold after finely grinding. The overall re-covery is more than 90. 84 % for ores in this deposit,meaning favorable ore-dressing conditions.
