中文摘要: 某难处理金矿先在氩气气氛下高温脱砷，脱砷后的金矿在氧气气氛中高温脱硫。并考察工艺参数对脱砷和脱硫的影响。结果表明，优化的脱砷条件为温度600 ℃、时间2 h、氩气流量200 mL/min，在该条件金矿中98%的砷以As2O3形式被挥发脱除，同时矿中26%的硫被脱除。优化的脱硫条件为温度650 ℃、时间2 h、氧气流量200 mL/min，在此条件金矿中97%的硫被挥发脱除。
Abstract:One refractory gold ore was first treated in the atmosphere with argon gas at a high temperature to remove arsenic and sulfur was removed from the residue obtained. The effects of technological parameters on dearsenization and desulfurization were investigated. The results show that 98% of arsenic from the ore is removed in the form of As2O3 and 26% of sulfur is removed under the optimum conditions including temperature of 600 ℃, time of 2 h, and argon flow rate of 200 mL/min. The sulfur removal rate is 97% under the optimum conditions including temperature of 650 ℃, time of 2 h, and oxygen flow rate of 200 mL/min.
