针对陕西某含碳高砷微细粒难处理金矿矿石性质，进行了提金工艺探索。试验结果表明：相比化学预处理—氰化浸出、氧化预处理—氰化浸出工艺，次氯酸钠浸金工艺可获得较为理想的回收指标；采用次氯酸钠二段浸出，金总浸出率可达到77．04％。
This paper conducts tests on gold recovery methods according to the property of one carbonaceous and highly arsenic microgranular gold ore from Shaanxi.The results show that the chemical pretreatment-cyanidation and oxidation pretreatment-cyanidation processes are outplayed by NaClO leaching process in achieving satisfactory in-dex.The two-phase NaClO leaching process can obtain a total gold leaching rate as high as 77.04 %.
