摘　　要：采用混合非氰药剂对某微细浸染型金矿进行了实验室浸出试验研究。优化后的工艺条件为：Q-1用量50 kg/t,Q-3用量105 kg/t,充气量1.8 m3/h,液固比2,常温搅拌24 h;搅拌后矿浆直接采用非氰药剂SZS浸出,浸出条件为：SZS用量4.4%,Cu2＋浓度0.06 mol/L,NH3·H2O浓度1 mol/L,Na2SO3浓度0.15 mol/L,液固比3,p H值10~11,常温搅拌4 h,在此条件下可获得金浸出率85.35%的指标。A laboratory leaching test was carried out for a micro-disseminated gold ore using mixed non-cyanide reagent.The process conditions were optimized as follows： firstly strengthened leaching was conducted with dosage of Q-1 and Q-3 at 50 kg / t and 105 kg / t,respectively,an aeration rate at 1. 8 m3/ h,liquid-solid ratio at 2,and agitation at room temperature for 24 h. After agitation,the slurry was directly leached using non-cyanide reagent SZS,with SZS dosage at4. 4%,Cu2 ＋concentration at 0. 06 mol / L,NH3·H2O concentration at 1 mol / L,Na2SO3 concentration at 0. 15 mol / L,liquid-solid ratio at 3,p H value at 10 ~ 11,with agitation at room temperature for 4 h. The test resulted in a leaching rate of 85. 35%.
