摘要
对用硫粉和氢氧化钠制备硫代硫酸钠和多硫化钠混合浸金体系的反应条件进行了实验，该制备反应的最佳条件是：搅拌速度200r／min、反应时间30～40min、温度353K、NaOH与S摩尔比1．5、氧气压力1．1MPa。该条件下得到的混合溶液中，S2O3^2-浓度较高。
The preparation of sodium thiosulfate and sodium polysulfide mixture for gold leaching, with the reagent of sulphur and sodium hydroxide, was studied by the experiments. The results show that the optimum reaction conditions are as follows： mixing speed 200 r/min, reaction time 30-40 min, temperature 353 K, mol ratio of NaOH and S is 1. 5, oxygen pressure 1： 1 MPa. Under this condition, the concentration of S2O3^2- in the mixture system was maximal.
