An interpretation of the association is given according to the fact that the content of re-duced sulfur in the ore-forming solution is much high relative to Cl in this kind of ore deposits,especially for the Au-Sb-As with W, using the data on their complexes and solubility. The highfineness of gold and the separation of gold from the base metals Cu, Pb, Zn, and sometimesfrom Ag in this kind of ore deposits are also interpreted.展开更多
文摘The occurrences and characteristics of the association of An-Sb-As-W are summa-rized. An interpretation of the association is given according to the fact that the content of re-duced sulfur in the ore-forming solution is much high relative to Cl in this kind of ore deposits,especially for the Au-Sb-As with W, using the data on their complexes and solubility. The highfineness of gold and the separation of gold from the base metals Cu, Pb, Zn, and sometimesfrom Ag in this kind of ore deposits are also interpreted.
