中文摘要: 以某高砷、高硫金矿在氩气气氛下高温脱砷样品为原料,研究脱硫温度、时间和氧气流量对酸性氯酸钠溶液提金的影响。结果表明,在脱硫温度650 ℃、氧气流量200 mL/min、脱硫时间2 h的条件下,金的浸出率可达95%。
中文关键词: 高砷、高硫难处理金矿 脱硫预处理 酸性氯酸盐提金
Abstract:Dearsenization pretreatment of refractory gold ore with high arsenic and sulfur bearing was conducted in argon atmosphere at high temperature. The effects of desulfurization temperature, time and oxygen flow rate on gold leaching rate with aqueous chlorate solution were investigated with dearsenization sample as raw materials. The results show that gold leaching rate is 95% above under the conditions of desulfurization temperature of 650 ℃, oxygen flow rate of 200 mL/min, and duration of 2 h.
