Types and distribution of silver ore deposits in China

Silver is generally recovered as a by and coproduct along with Au, Pb, Zn, Cu, Sb, Bi, Hg, Sn and W from polymetallic and gold mines in China. Chinese silver deposits can be classified into five principal types according to host rocks. These types and their host rocks are: (1) marine volcanicsedimentary rocks hosting (la) massive sulfide PbZn(Cu)Ag ores and (1b) stratiform Ag(Au) ores
