针对西准噶尔吉尔吾沙克金矿床的金矿石，进行详细工艺矿物学研究，并在此基础上开展可选性试验。结果表明：矿石中有价元素为Au，品位为3.61 g/t；金矿物种类为自然金、银金矿、金碲矿、金硒银矿，嵌布状态有包裹金、裂隙金和晶间金，粒度主要为微粒（0.2 ~ 10.0 μm），个数占96.96%，细粒及以上金颗粒（> 10 μm）占3.04%；选矿试验推荐采用浮选-浸出联合流程工艺：浮选—浮选精矿Au品位53.14 g/t，回收率31.69%，浮选尾矿全泥浸出24 h后，尾渣含金0.20 g/t，金作业浸出率89.56%，联合流程Au的总回收率达93.31%，各项指示比较理想。

Based on the detailed process mineralogy of gold ore from Jierwushake gold deposit in west Junggar, the selectability test was carried out. The results show that the valuable element in the ore is Au with a grade of 3.61 g/t. The types of gold minerals are natural gold, silver-gold, gold-tellurium and gold-selenium-silver ore, and the embedded states are encapsulated gold, fracture gold and intergranular gold. The particle size is mainly microparticle gold (0.2 ~ 10.0 μm), accounting for 96.96%, and the number of fine and above gold particles (> 10 μm) account for 3.04%. The flotation-leaching combined process is recommended for mineral processing test: the Au grade of flotation-flotation concentrate is 53.14 g/t, and the recovery rate is 31.69%. After leaching the whole sludge of flotation tailings for 24 hours, the gold content in tailings is 0.20 g/t, and the leaching rate of gold operation is 89.56%, the Au total recovery rate of combined process is 93.31%, and the instructions are ideal.
