摘要
由Ｂｉ２Ｓ３在ＮａＣｌ溶液中的溶解度，Ｂｉ２Ｓ３－Ｃｌ－Ｈ２Ｏ系的电位-ｐＨ、电位-ｌｇ［Ｃｌ］图分析表明：Ｂｉ２Ｓ３矿在氯盐水溶液的溶解度有了很大的提高，在矿浆电解时它同时存在三种浸出机理，即１．化学溶解．２．化学氧化．３．阳极氧化溶液中Ｃｕ（）与离子Ｆｅ（）的存在有利于Ｂｉ２Ｓ３矿的浸出．
Analysis of solubility of Bi2S3 in natriUm chloride salt solution and E-pH, E-lg[Cl-] duagrans if Bi2S3-Cl-H2O system shows that the solubility of Bi2S3 in natrium chloride salt solution is improved obviouslyand three leaching mechanisms of Bi2S3 in electro-slurry process may occur simultaneously:1. Chemical dissolution : 2. Chemical oxidation: 3. Anodic oxidation: The existence of Fe3+ ion and Cu2+ ion in solution is beneficial to the leaching of Bi2S3
