对１４种可能与硫化铜矿物和黄铁矿表面上的金属离子发生螯合作用的药剂在浮选中的效果进行了评价。所研究 的药剂属于巯基苯基衍生物、硫代氨基甲酸盐、硫脲、咪唑衍生物、肟、羟基喹啉和黄原酸基甲酸盐。咪唑啉（１－羟 乙基－２－十七烷基）是硫化铜矿物最好的捕收剂，但是它也是黄铁矿的优良捕收剂。其结构作某些改变可降低它 对黄铁矿的捕收能力，但是它对硫化铜矿物的捕收能力也同时降低。这些捕收剂的结构改变和矿浆ｐＨ变化都会 改变药剂的捕收性质。用这些捕收剂浮选矿物的顺序如下：黄铜矿＝辉铜矿＞铜蓝≥斑铜矿＞＞黄铁矿。孔雀石 浮选与硫化钢浮选类似，这表明矿物品格中的钢是捕收剂固着的特效组分。
The flotation effect of 14 agents that may chelate metal ions on the surface of copper sulfide minerals and pyrite was evaluated. The agents studied belong to the group consisting of mercaptophenyl derivatives, thiocarbamates, thioureas, imidazole derivatives, oximes, quinolinol and xanthogenates. Imidazoline (1-hydroxyethyl-2-heptadecyl) is the best collector of copper sulfide minerals, but it is also an excellent collector for pyrite. Some changes in its structure reduce its ability to capture pyrite, but its ability to trap copper sulphide minerals also decreases. Structural changes in these collectors and changes in pulp pH can alter the trapping properties of the agent. The sequence of flotation of minerals with these collectors is as follows: Chalcopyrite = Chalcocite> Copper Blue ≥ Bornite> Pyrite. Malachite flotation and sulfide steel flotation is similar, indicating that the mineral character of the steel collector is the fixation of the special effects components.
