摘要/Abstract

摘要： 某含金1.85 g/t的汞冶炼渣中金主要以游离微细金和硫化物包裹金的形式存在，对该二次资源进行了浮选回收金的试验研究。结果表明，在磨矿细度为-0.074 mm占80%的情况下，采用1粗2精2扫、中矿顺序返回流程处理该试样，可以获得金品位为28.65 g/t、回收率为68.45%的金精矿，导致金回收率不高的主要原因是金颗粒微细和被碳酸盐、褐铁矿、石英和硅酸盐等矿物包裹。

Abstract: Gold exists in the form of free fine gold and gold-wrapped sulfide in mercury smelting slag with gold bearing of 1.85 g/t.Research on recovering gold by flotation from the secondary resources was carried out.The research results showed that under grinding fineness of -0.074 mm 80%，gold concentrate with gold grade of 28.65 g/t，and recovery of 68.45% was obtained by the flow sheet of one-roughing，two-cleaning，three-scavenging and middles back to the process in order.The main reasons resulting in low gold recovery are that gold occurs in ultra-fine particles or was wrapped by carbonates，limonite，quartz and silicate.

Key words: Gold-bearing mercury sinelting slay, Freefine gold,Gold-wrapped sulfide, Secondary resources
