The authors find that morpholine dithiocarbamate (MDTC) and S-cyanoethyl N, N-diethyl dithiocarbamate (CEDETC) are capable to form stable compounds with gold in the solution and to form an adsorption layer on the surface of gold-bearing sulphides, which points at them as new selective collectors for gold recovery from rebellious ore. The coating area of MDTC on the surface of chalcopyrite, arsenopyrite and pyrite, with new discrete growths is quantitatively assessed. CEDETC improves floatability of chalcopyrite by 1.5–2.0 times as against butyl xanthate at low consumption of reagents, while difference in floatability of chalcopyrite and arsenopyrite considerably grows, which is indicative of a beneficial effect on production of Au-Cu concentrates with lower As content by flotation.

基于环胺和脂肪胺的二硫代氨基甲酸盐对金矿浮选的络合吸附性能分析

作者发现吗啉二硫代氨基甲酸酯 (MDTC) 和 S-氰乙基 N, N-二乙基二硫代氨基甲酸酯 (CEDETC) 能够与溶液中的金形成稳定的化合物，并在含金硫化物表面形成吸附层，这表明在他们作为新的选择性收集器从叛逆的矿石中回收黄金。MDTC 在黄铜矿、毒砂和黄铁矿表面的涂层面积，以及新的离散生长被定量评估。CEDETC 在试剂用量低的情况下，将黄铜矿的可浮性比丁基黄药提高了 1.5-2.0 倍，而黄铜矿和毒砂的可浮性差异显着增加，这表明对生产砷含量较低的 Au-Cu 精矿有利浮选。
