The sediment of sulfide can be separated from the solution by filtration and syphon. After the sediment is dissolved by diluted nitric acid, Ni 2+ and Co 2+ in solution can be determined by the flame atomic absorption spectrometry method.

将沉淀过滤，或者加入明矾以加速硫化物的沉降、凝结，再用虹吸法吸去上层清液的方法将沉淀分离，用热稀硝酸将沉淀溶解后直接用火焰原子吸收法测定镍、钴的含量。

Moreover, copper and silver in silver sulphosalts of the tetrahedrite group show negative correlation, and their high or low silver content bears no relation to at atomic proportion and Sb/ ratio.

这些矿床的矿石矿物组合和银硫盐矿物多在主要硫化物之后晶出的产状特征及其化学成分的近似性，反映出成矿溶液成分及成矿作用演化的相似性。

The AVS-SEM distribution in the sediments of Guanting Reservoir and Yongding River was studied and the metal concentration in the water above the sediments and the pore water was measured. Based on the results, the reaction between the sediments and metal ions were discussed and the heavy metal pollution of the sediments in Guanting Reservoir and Yongding River was evaluated preliminarily.

官厅水库沉积物，由于处于缺氧性环境，沉积物中的酸可挥发性硫化物控制着大多数金属离子在沉积物和孔隙水两相间的分配，本文通过现场采样，分析了官厅水库和永定河沉积物中的AVS—SEM的分布，同时测定了沉积物上覆水以及部分样点的孔隙水中的重金属浓度，探讨了沉积物与重金属离子的作用；并根据采样分析结果对官厅水库及永定河沉积物中的重金属污染做了初步评价。

The major methods involved in this paper are cyanidation,thiocarbamide process,thiocyanate process,thiosulfate process, multi-sulfide process,haloid process,and other reagents procss;the advantages and disadvantages of the methods as well as the suitability of these methods for treating various silver bearing ores are generally analyzed.
