摘　　要：河南某金选厂矿石主要为细粒嵌布含金硫化矿,为了实现矿石中金的高效回收,降低生产成本,本研究根据含金硫化矿原矿性质特点,采用柱机联合一粗一精一扫浮选工艺,对其进行了半工业试验。通过条件试验确定了最佳试验参数。当试验原矿品位为5.11 g/t时,试验最终得到回收率88.80%、品位为65.77 g/t的合格精矿。试验结果表明在试验回收率与工业相当的前提下,半工业浮选工艺具有提高金精矿品位约10.00 g/t并缩短工艺流程的优势。The ore of a gold processing plant in Henan province are mainly t-me-disseminated gold-bearing sulfide ore. In order to achieve efficient recovery of gold from ore and reduce production costs ,this research was done based on characteristics of the gold-bearing sulfide ore, and the semi-industrial testt was processed with column machine combination-one roughing, one scavenging, one cleaning. The optimum parameters of experiment were determined by condition tests. When ore grade is 5.11 g/t, the semi-industrial test finally obtained qualified concentrate which recovery rate was 88.80%,and the concentrate grade was 65.77 g/t. The result shows that based on the similar recovery of industry and semi industry, semi-industrial flotation process can improve the grade of gold concentrate about 10.00 g/t and shorten the process.
