摘　　要：研究了海藻酸钠在丁铵黑药捕收剂体系下对方铅矿和黄铜矿的抑制作用,并通过动电位、红外光谱、X射线光电子能谱等考察了海藻酸钠对黄铜矿及方铅矿的作用机理。结果表明,海藻酸钠能在不影响黄铜矿浮选行为的同时对方铅矿产生强烈抑制作用,使方铅矿浮选回收率从87.68%降至8.7%。The selective depression effect of sodium alginate on chlorite and chalcopyrite with ammonium dibutyl dithiophosphate as the collector system was investigated by means of electrokinetic potential,infrared spectrum,and X-ray photoelectron spectroscopy.The results show that the usage of sodium alginate can lead to a strong depression of galena without the flotation behavior of chalcopyrite affected.Consequently,the flotation recovery of galena is reduced from 87.68%to 8.7%.
