【摘要】 对富锗硫化锌精矿进行了加压氧化酸浸锗、浸出溶液中和沉淀分离锗的试验研究,结果表明,加压浸出在温度145～ 155℃、氧气分压1.2MPa、时间2.0h、精矿粒度-38μm占96.60%、硫酸用量55 ml/100g 精矿的条件下,锗的浸出率可以达到91%以上;加压浸出溶液石灰石粉中和沉淀分离锗,锗的沉淀率可以达到96%以上,沉锗渣中锗的品位可以达到 300g/t 左右。更多还原

【Abstract】 An experimental study which treat zinc sulfide concentrate containing rich germanium using pressure-oxidation leaching and neutralization precipitation germanium from leaching solution was put up.The results show that under the conditions which were leaching temperature 145～155℃, oxygen pressure 1.2 MPa,leaching time 2 h, granularity-38 μm 96.60% and acid 55 ml per 100 g concentrate,the leaching rate of germanium was above 91%.The leaching solution was neutralized using limestone powder for precipitating germanium, precipitating rate was above 96%,and the content of germanium sediment from precipitating was about 300 g/t.更多还原
