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.
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.
