用不同的螯合物药剂,即 N-亚哨基苯胺铵(铜铁灵)、8-羟基喹啉、a-苯偶姻肟和二乙基硫代氨基甲酸钠进行了氧化铜矿的阶段选矿试验。试验的这四种捕收剂中已发现二乙基硫代氨基甲酸能有效地达到高的回收率和品位。与其他捕收剂相比,这种药剂的消耗量也较低。所有这几种捕收剂对铜都有很好的选择性并且得到了优质精矿。吸附研究指出,在矿物表面上捕收剂的吸附依从一个真正的化学反应。二乙基硫代氨基甲酸络合物性质的研究指出,在矿物表面上的每一个铜原子将和两个二乙基硫代氨基甲酸分子络合,研究了药剂浓度,矿浆的 pH 值,叶轮速度等参数。
Phase beneficiation of copper oxide was carried out with different chelate agents, namely N-sentine Aniline (Cucurbit), 8-hydroxyquinoline, a-benzoinoxime and sodium diethyl thiocarbamate test. It has been found in these four collectors tested that diethylthiocarbamic acid can effectively achieve high recovery and grade. Consumption of this agent is also lower than other collectors. All of these collectors have a good selectivity for copper and high-quality concentrates. Adsorption studies indicate that the adsorption of collectors on the mineral surface follows a real chemical reaction. Diethyl thiocarbamate complex properties of the study pointed out that in the mineral surface of each copper atom and two diethyl thiocarbamic acid molecular complex, studied the concentration of the agent, the pH of the pulp, the impeller Speed and other parameters.
