载铟闪锌矿>黄铁矿。铜离子的吸附量试验表明,同等条件下,载锗闪锌矿和黄铁矿对铜离子的吸附量分别为最大和最小。高碱条件同样不利于铜离子的吸附。载铟和载锗闪锌矿表面的丁黄药和丁胺黑药的吸附量与铜离子的吸附量成正比,而铜离子的添加反而降低黄铁矿表面对丁黄药和丁胺黑药的吸附量。活化后的3种矿物在整个p H范围内对乙硫氮的吸附量并没有明显的提高。 The flotation and adsorption experiments were carried out to study the effects of butyl xanthate, butylamine black, diethylthiourea and copper sulfate on the flotation behavior of Indium-loaded sphalerite, germanium sphalerite and pyrite. The results show that in the absence of activator and other experimental conditions, the flotation rates of the three kinds of minerals in the three collector systems reached the highest and the lowest respectively in the butyl xanthate and diethylsulfate systems. In the butyl yellow drug and butylamine black drug system, the three kinds of minerals in the acidic conditions, the highest rate of floating and adsorption, which pyrite> indium sphalerite> germanium sphalerite; under alkaline conditions , The floatability of 3 kinds of minerals and the amount of collector adsorbed obviously decreased. In the B-S system, the three minerals have the best floatability at 6

indium sphalerite > Pyrite. Copper ion adsorption experiments show that under the same conditions, germanium-loaded sphalerite and pyrite adsorption of copper ions were the largest and the smallest. High alkali conditions are also detrimental to copper ion adsorption. The adsorption capacity of butyl xanthate and butylamine black on indium and germanium-bearing sphalerite is proportional to the adsorption of copper ions, while the addition of copper ion on the surface of pyrite reduces the toxicity of butyl xanthate and butylamine black drug The amount of adsorption. There was no significant increase in the adsorption of diethylthiourea over the entire pH range for the three activated minerals.
