摘要
本文针对成分复杂金精矿的特点,采用焙烧-氰化浸出工艺,通过实验研究了铜、硫、碳和砷等元素对氰化过程的影响,并在生产上对金精矿焙烧-氰化浸取金银技术进行了改进,使复杂金精矿中金银的浸出率得到明显提高,并获得了可观的经济效益。
According to the characteristics of complex gold concentrate,the paper studied the effect of impurity element such as copper,sulfur,carbon and arsenic on cyanidation process and improved the roast-cyanidation technique in production,thus,the extraction rate increased distinctly and the considerable economic benefits was obtained.
