中文摘要: 对某低品位含金硫精矿开展氧压酸浸产元素硫、碱硫氧压浸取金银试验。酸浸试验最佳条件为：浸出温度130 ℃、浸出时间300 min、浸出压力1.6 MPa、液固比4︰1、始酸浓度20 g/L、木质素2‰；碱硫氧压浸金试验最佳条件为：浸金剂（石灰+硫磺）为总干矿的40%、硫碱质量比0.35、催化剂Cu(NH3)42+ 0.06 mol/L、活化剂木质素占干矿的0.2%、氧压0.4 MPa、温度105 ℃、浸金时间5 h，在此条件下金、银的浸出率分别为88.23%和61.35%。
Abstract:Gold and silver were leached from low grade gold-bearing sulfur concentrates by alkali-sulfur oxygen pressure leaching. The optimum acidic leaching conditions including leaching temperature of 130 ℃, leaching time of 300 min, leaching pressure of 1.6 MPa, L/S of 4︰1, initial concentration of acid of 20 g/L, and lignin of 2‰. The optimum sulfur-alkali oxygen pressure leaching conditions include leaching agent of 40% of total dry ore, mass rate of sulfur to alkali of 0.35, catalyst Cu(NH3)42 of 0.06 mol/L, sodium lignosulphonate of 0.2% of dry ore, oxygen pressure of 0.4 MPa, temperature of 105 ℃, and leaching time of 5 h. The leaching rate of gold and silver is 88.23% and 61.35% respectively under these optimum conditions.
