合成Cu_2S的氧压酸浸在高压釜内进行,温度范围为80℃～120℃,压力为1.01～4.05MPa,硫酸浓度为0.28N～2.14N,添加铁离子浓度最高为0.46g/l,搅拌速度为800r.p.m。主要考查了铁离子添加量及其他条件对浸出过程第二阶段的影响。添加铁离子使浸出速度加快,元素流产率提高。Fe_3~+与CuS反应,生成Fe~(2+),在Cu~(2+)存在下, The oxygen pressure of the synthesized Cu 2 S is immersed in an autoclave at a temperature in the range of 80 ° C. to 120 ° C. and a pressure of 1.01 to 4.05 MPa with a sulfuric acid concentration of 0.28 N to 2.14 N and a maximum iron ion concentration of 0.46 g / Speed ​​is 800r.pm. Mainly examined the iron content of iron and other conditions on the second phase of the leaching process. Add iron ions so that the leaching rate, elemental abortion increased. Fe_3 ~ + reacts with CuS to form Fe ~ (2+). In the presence of Cu ~ (2+)
