对含Ｃｕ、Ｚｎ等耗氰矿物的浮选金精矿，采用“在常温常压下及中碱性介质中以预处理剂浸出除杂，然后氰化”的工艺，金浸出率可达９５％以上，氰化钠耗量低于５ｋｇ／ｔ。对精矿脱药方式和再磨细度、预处理时间、预处理剂浓度、预处理剂耗量和循环再生性能、矿石适应性能等工艺条件及预处理剂残余物对后续氰化浸出和锌置换的影响的研究表明，该工艺具有操作简便、药耗低、母液循环再生性能良好和氰化浸出指标可靠等特点。 For flotation gold concentrates containing cyanide minerals such as Cu and Zn, the gold leaching rate can reach 95 with the process of “leaching out impurities and then cyaniding” under normal temperature and normal pressure and medium-alkaline medium. %, Sodium cyanide consumption of less than 5kg / t. The leaching method of concentrate and resharpening fineness, pretreatment time, pretreatment agent concentration, pretreatment agent consumption and recycling performance, ores adaptability and other process conditions and pretreatment agent residue on the subsequent cyanidation leaching and zinc Studies on the effect of displacement show that the process has the characteristics of simple operation, low drug consumption, good recycling performance of mother liquor and reliable indicator of cyanidation leaching.
