对新型Mac-12进行了普遍化微扰理论研究,结果表明,Mac-12中反应中心硫原子给电子的能力较弱,而接受反馈电子的能力很强,其对提供反馈电子能力较弱的黄铁矿的捕收能力弱,而对易提供反馈电子的黄铜矿的捕收能力强。工业试验结果表明,Mac-12对硫化铜矿物和氧化铜矿物具有强亲固能力,与传统黄药工艺相比,Mac-12与少量丁黄药工艺混用可降低铜硫浮选分离中的石灰用量,铜精矿中铜品位提高0.93个百分点,铜回收率提高1.03个百分点;金品位提高1.29 g/t,金回收率提高7.16个百分点;钼品位提高0.0293个百分点,钼回收率提高3.90个百分点。Mac-12已工业应用于德兴铜矿,取得了较好的经济效益。
The generalized perturbation theory of the new Mac-12 shows that the sulfur atom in the reaction center of Mac-12 possesses a weak ability to donate electrons and a strong ability to accept feedback electrons, which is weak to provide feedback electrons Pyrite has a weak catch capability and a good ability to catch chalcopyrite, which provides easy feedback electronics. Industrial test results show that Mac-12 has strong affinity for copper sulfide minerals and copper oxide minerals. Compared with traditional xanthate technology, Mac-12 can reduce the separation of copper and sulfur flotation when mixed with a small amount of butyl xanthate Of the amount of lime, copper grade copper concentrate increased 0.93 percentage points, copper recovery rate increased 1.03 percentage points; gold grade increased 1.29 g / t, gold recovery rate increased 7.16 percentage points; molybdenum grade increased 0.0293 percentage points, molybdenum recovery rate increased 3.90 percentage points. Mac-12 has been industrial applications Dexing Copper Mine, achieved good economic returns.
