| 摘 要： | 针对新疆某热液蚀变型岩金矿,采用重选—氰化联合工艺进行了提金试验研究。试验结果表明,在重力值为60 G、流态化水量为3.5-4.0 L/min的条件下,尼尔森重选过程可优先富集金品位为311.70×10^-6、回收率为42.23%的粗粒金精矿;在磨矿细度为-0.045 mm占90%、矿浆浓度为40%、氰化时间为24 h的条件下,重选尾矿氰化过程可获得金浸出率为97.41%。因此,重选—氰化联合工艺可获得金综合回收率为98.81%。

| Abstract: | Gravity separation and cyanidation combined process was applied on the hydrothermal alteration types gold ore in Xinjiang Province.The test results revealed that coarse gold concentrate with grade of 311.70 ×10^-6 and recovery of 42.23%was obtained using Knelson centrifugal separator under the conditions of gravity value of 60 and fluidzed water volume of 3.5-4.0 min^-1.Gold leaching efficiency of gravity separation tailings was 97.41%using cyanidation process under the conditions of milling size of-0.045 mm 90%,cyaniding time of 24 h and pulp density of 40%.Therefor, the total recovery of gold ore was 98.81% using gravity separation and cyanidation combined process. |
