我公司与西安有色金属研究所合作,用巯基乙酸钠代替氰化物的试验研究。工业试验于84年9月至85年10月上旬在金堆城钼业公司科研所试验厂先后共做四次工业试验。试验结果,用巯基乙酸钠代替氰化物是可行的。产出的商品钼精矿的组成全部符合标准,精选回收率与用氰化钠时相同,用量等于氰化钠用量二分之一。试验结果表明巯基乙酸钠是黄铜矿,黄铁矿有效抑制剂,可用于钼和铜钼矿石浮选,与氰化钠比较巯基乙酸
My company and the Xi’an Institute of Nonferrous Metals, with sodium thioglycolate instead of cyanide pilot study. Industrial tests from September 1984 to early October 85 early in the Jinduicheng Molybdenum Research Institute pilot plant has done a total of four industrial tests. Test results, the use of sodium thioglycolate instead of cyanide is feasible. The composition of molybdenum concentrate produced is all in accordance with the standard. The selected recovery rate is the same as that of sodium cyanide, and the dosage is equal to one half of that of sodium cyanide. The test results show that sodium thioglycolate is an effective inhibitor of chalcopyrite and pyrite and can be used for flotation of molybdenum and copper-molybdenum ore. Compared with sodium cyanide, mercaptoacetic acid
