对日本生产金和银的3种类型的矿床中的Ag/Au总产量比和金-银矿物进行了总结。这些矿床包括:金-银脉(1—A型),贱金属脉[Cu,Pb,Zn,Mn,(Sn),(W),(Bi),(Mo),(Sb)](1—B型),富金浸染型矿床(2型)。一般,贱金属富集的矿床(1—B型)具有下述特征:①Ag/Au总产量比值高;②主要的银矿物是Se贫的辉银矿,有时候是银的硫酸盐(深红银矿,硫锑铜银矿,银镍黝铜矿); The total Ag / Au yield and gold-silver minerals in the three types of deposits produced in Japan for gold and silver are summarized. These deposits include gold-silver veins (type 1-A), base metal veins [Cu, Pb, Zn, Mn, (Sn), (W), (Bi), (Mo) B), gold-rich disseminated deposits (2). In general, base metal-rich deposits (Type 1-B) have the following characteristics: ① high ratio of total Ag / Au output; ② the main silver mineral is Se-poor galena, sometimes silver sulphate Silver, sulfur antimony copper silver, silver nickel tetrachloride);
