【摘要】 计算并绘制了Cu-As-H2O系的电位-pH图,对高砷硫化铜矿细菌浸出液制备砷酸铜的过程进行了热力学分析。细菌氧化浸出可同时浸出Cu和As,根据不同的pH值和铜砷比,得到了组成不同的砷酸铜(CuHAsO4、Cu5H2(AsO4)4、Cu2AsO4OH)。更多还原

【Abstract】 Potential-pH diagram of Cu-As-H2O system was calculated and depicted, the thermodynamic analysis of copper arsenate preparation from high arsenate copper sulfide ore leaching liquor has been made. According to different pH and [Cu] T/[As] Tratio,the different shape copper arsenate:CuHAsO4、Cu5H52(AsO4) 4 Cu2AsO4OH and can be formed.更多还原
