COMPUTER AIDED MOLECULAR DESIGN FOR THE HIGH SELECTIVITY COLLECTORS OF CHALCOPYRITE AND PYRITE

将计算机辅助分子设计应用到选矿药剂分子设计中,对黄铜矿和黄铁矿高选择性捕收剂进行设计,得出了合适的极性基团和非极性基,即目的新型捕收剂。在实验室合成了目的药剂,进行了黄铜矿和黄铁矿纯矿物浮选试验,浮选分离效果显著。初步验证了计算机辅助分子设计在选矿药剂分子设计中的可行性。

Using the method of computer-aided molecular design to the designing of flotation reagents, this paper describes the way of designing highly-selective collectors for chalcopyrite and pyrite, deriving suitable polar and non-polar groups of the goal collectors. These novel collectors are synthesized in laboratory and applied to pure-mineral flotation tests. The good result of separation indicates the promising feasibility of applying computer-aided molecular design in designing mineral processing reagents.
