新民铜银多金属矿床的矿体呈脉状、透镜状和似层状产出,主要受断裂、接触带和隐爆角砾岩筒构造控制。金、银主要呈自然金、自然银、辉银矿(β-Ag2S)-螺状硫银矿(α-Ag2S)、硫铋铅银矿、角银矿和碘银矿等独立矿物存在.金的主要载体矿物为毒砂、褐铁矿、辉铋矿、方铅矿、黄铁矿和黄铜矿。配分计算结果表明:在原生矿石中,黄铁矿中金的配分率较高;而方铅矿、黄铁矿和黄铜矿中银的配分率较高.在氧化矿石中,褐铁矿中金、银的占有率均较高.根据金、银的赋存状态特征,对该区金、银的综合利用进行了初步评价.
The Xinmin copper-silver polymetallic deposit has a vein-shaped, lens-like and laminar-like distribution and is mainly controlled by faults, contact zones and cryptoexplosive breccia tubes. Gold and silver are mainly in the form of natural gold, natural silver, β-Ag2S-α-Ag2S, bismuth-lead-silver ore, angle silver and iodine silver ore. The main carrier minerals of gold are arsenopyrite, limonite, bismuthinite, galena, pyrite and chalcopyrite. The results of the partitioning calculation show that in the primary ore, the distribution ratio of gold in pyrite is high, while the distribution ratio of silver in galena, pyrite and chalcopyrite is higher. In the oxide ore, limonite gold, silver share is higher. According to the characteristics of gold and silver occurrence status, the comprehensive evaluation of the comprehensive utilization of gold and silver in the area was carried out.
