| 摘 要： | 本文研究了盐湖形成过程中银的迁移形式及富集条件．在热液中银主要以Ａｇ（ＨＳ）￣－＿２·Ａｇ（ＮＨ３）·ＡｇＣｌ络合物形式迁移；在表生条件下银主要以Ａｇ（Ｓ２Ｏ３）络合物形式迁移．它们在盐湖中被演化为ＡｇＣｌ络合物，由于湖水大量蒸发、盐类大量结晶析出，导致盐湖卤水中银的富集．

| Abstract: | In this paper mobility formation and caaumulation condition of silver were studied in forming process of salt lake. The silver mobilizes mainly with the form of complex Ag (HS)￣-_2, Ag (NH3)￣+_2, AgCl￣-_2; under the hypergenic condition. it is with the form of complex Ag (S2O3)￣3-_2. They are evolved complex AgC1￣-_2 in salt lake. Because of large quantity of lake water evaporation and crystal separation from salts, which leads to accumulate the silver in salt lake brine. |
