中文摘要:
      本文针对某微细粒含砷含碳难处理金矿进行了浮选试验研究,在磨矿细度-0.074mm含量为90%条件下,采用浮选条件试验确定的最佳药剂制度,在两粗三精三扫闭路浮选流程条件下,可以获得精矿金品位为41.90%,金回收率为80.64%的浮选指标。工艺矿物学研究结果表明,尾矿中金主要以微细粒贫连生体硫化物、硫化物又包裹金的形式存在,采用浮选工艺难以有效回收。
英文摘要:
      In this paper, the flotation test of a tiny refractory gold ore containing arsenic and carbon is investigated. After the feed ore was milled to a grinding fineness of -0.074mm 80%,a closed-circuit flow sheet consisting of two stages of roughing,three stages of cleaning and three stages of scavenging was adopted in the experimental study under the optimum flotation reagent conditions, obtains a gold concentrate grading 41.90% at 80.64% recovery. Research results of mineralogy show that gold in tailings mainly exists in the form of fine and poor conjoined sulfide and encapsulating sulfide which is difficult to recover effectively by flotation process.
