烷基 /烯丙基和乙氧羰基硫代氨基甲酸酯和乙氧羰基硫脲是铜的选择性捕收剂 ,在黄铜矿和被铜离子活化的闪锌矿与黄铁矿的浮选分离中具有良好的应用潜力 ,其捕收能力与乙黄药相当 ,但选择性更好 ,它对黄铁矿的捕收能力较弱 ,特别是在中性pH条件下更为明显。矿物充氧搅拌对硫化矿的分离起好的作用。根据浮选结果、X射线光电子能谱和瞬时二次离子质谱结果 ,提出了这些捕收剂与硫化矿物相互作用机理。 Alkyl / allyl and ethoxycarbonyl thiocarbamates and ethoxycarbonylthioureas are selective collectors of copper in chalcopyrite and copper ion-activated sphalerite and pyrite floating Selective separation has good potential applications, its capture capacity and yellow drug comparable, but better selectivity, its ability to capture the weak pyrite, especially under the conditions of neutral pH is more obvious. Oxygenation of minerals mixing sulfide minerals played a good role in the separation. According to the results of flotation, X-ray photoelectron spectroscopy and instantaneous secondary ion mass spectrometry, the interaction mechanism between these collectors and sulfide minerals is proposed.
