摘　　要：针对云南某黄金矿石进行了不同造渣剂配比的金泥造渣熔炼试验。结果表明:金泥造渣熔炼除杂时造渣剂配比选为硼砂7.5%、碳酸钠10%、二氧化硅2.5%,可获得较好的熔炼效果,合金渣中金品位从原工艺的21198.06 g/t降至221.5 g/t,银品位从原工艺的154386.55 g/t降至1962 g/t。The gold mud slag forming and smelting test with different slagging flux proportion was carried out for one gold ore in Yunnan.The test results show that the better smelting effect can be obtained when proportion of slagging flux is selected as 7.5% of borax,10% of sodium carbonate,2.5% of silicon dioxide during purification of gold mud slag forming and smelting;in the alloy slag,the gold grade is decreased from the original 21198.06 g/t to 221.5 g/t,the silver grade is decreased from the original 154386.55 g/t to 1962 g/t.
