中文摘要: 对某含砷金银精矿进行了酸性热压氧化单因素试验,在210 ℃、停留时间1.5 h、氧分压700 kPa、矿浆浓度20%、搅拌速度800 r/min的优化条件下得到金的回收率95.6%。针对银回收率低下的情况,在80~95 ℃用石灰对热压氧化矿浆进行银强化试验,结果显示银回收率有了大幅度提高,最高达86.3%。
Abstract:The effects of temperature, retention time, oxygen partial pressure, pulp density and stirring speed were investigated separately in the acidic pressure pre-oxidation experiment with a refractory gold ore containing arsenopyrite. A good gold recovery (95.6%) was obtained under 210 ℃, retention time of 1.5 h, oxygen partial pressure of 700 kPa, pulp density of 20% and stirring speed of 800 r/min. The silver recovery was improved substantially after the silver-enhancement at 80~95 ℃.
