| 摘 要： | 将黄铁矿、砷黄铁矿和含砷金精矿与碳酸钠和碳混合，进行了氧化焙烧的理论分析和试验研究。结果表明，在７２３～９７３Ｋ温度范围内，黄铁矿和砷黄铁矿中的硫和砷氧化生成非挥发水溶性硫酸钠和砷酸钠。当用水浸出焙砂时，砷和硫全部转入溶液中。水浸渣用二氧化硫气体处理后，用氰化法浸出残渣，可使金的回收率达９５．５％～９６％。

| Abstract: | Theoretical and
experimental data showed that if pyrite, arsenopyrite or arsenicgold concentrates, are mixed
with sodium carbonate and carbon, and then roasted, sulfur and arsenic can be transformed into
sulfate and arsenate at temperature 723973 K. Sulfate and arsenate are soluble and the
residues can be treated with SO2 and then with cyanide. The recovery rate for gold can reach
95. 5% to 96%. |
