摘要
对含砷金精矿固砷焙烧工艺条件进行了研究。用石灰作固砷剂 ,在 (6 5 0± 2 0 )℃下焙烧 1 80 min,固砷率 >95 % ,硫脲浸金的浸出率≥ 88%
The condition of fixing arsenic roasting process has been investigated. Using lime as fixing arsenic agent, the concentrate is roasted at 650±20 ℃ for 80 min, with fixing arsenic rate of more than 95%. The leaching rate of gold with thiourea ≥88%. [
