层控型铅锌硫化物矿床是铅锌矿床的重要类型之一。为了建立层控铅锌琉化物矿床成矿模式,作者进行了如下实验研究: 1.铅锌硫化物在含有机质、氯-水体系中的溶解度实验。实验是在含羧基、羟基等有机官能团的NaCl水体系中进行的。起始溶液pH值保持在6±。实验后溶液的pH值一般都有上升的趋势,但最高未超过8,但含有CH_3COO~-、羧基的溶剂时,实验后的pH值稍有下降,但均不低于3.5。实验结果部分数据见表(1)。
Layer-controlled lead-zinc sulfide deposits are one of the important types of lead-zinc deposits. In order to establish the stratabound lead-zinc-zinc ore deposit metallogenic model, the authors conducted the following experimental studies: 1. Solubility experiments of lead and zinc sulfides in organic-inorganic and chlorine-water systems. The experiment was carried out in NaCl water system containing organic functional groups such as carboxyl group and hydroxyl group. The pH of the starting solution was kept at 6 ±. After the experiment, the pH value of the solution generally has a tendency to rise, but the maximum does not exceed 8, but when the solvent containing CH_3COO ~ - and carboxyl group is used, the pH after the experiment slightly decreases, but both are not lower than 3.5. Part of the experimental data in Table (1).
