【摘要】 研究了胺类萃取剂从多硫化物含金贵液中金的萃取 ,考察了影响萃取的一些因素 ,实验结果表明 :胺类萃取剂可从弱碱性多硫化物含金贵液中萃取金。在同一萃取条件下 ,伯胺的萃取能力要强于叔胺的萃取能力。调节溶液的 pH值 ,用去离子水从含金有机相中反萃金。更多还原

【Abstract】 The extraction of gold (I) from containing gold polysulfide solution with amine alkyl extractants was studied.Several factors influencing the extraction were discussed.The experimental results show that only in low alkaline solution the gold (I) could be extracted.Under the same condition,the extraction capacity of primary alkyl amine N 1923 is better than that of tertiary alkyl amines TOA.By adjusting the pH of solution,it could strip gold from containing gold organic phase with deioned water.更多还原
