硫代硫酸盐浸金过程中硫代硫酸盐消耗浅探

摘要

Some important factors influencing thiosulfate consumption in dissolution of goldfrom ore using ammoniacal thiosulfate solutions containing Cu2+ were examined. These fac-tors include leaching time, Cu2+concentration,S2O23- concentration, pH values, oxygen andnitrogen atmosphere, etc. The catalytic reaction between thiosulfate and copper ions,whichresults in excess amount thiosulfate consumption,was verified in tests described in this pa-per. The consumption of thiosulfate can be reduced by controlling the concentration of cop-per ions and oxygen.%研究室温下硫代硫酸盐浸金过程中影响硫代硫酸盐肖耗的各种因素，包括浸出时间、铜浓度、pH、氧气、氮气等。铜氨络离子与氧气同时作用于硫代硫酸盐是该盐在浸金过程中大量消耗的主要原因。
