摘要： 研究了羟肟类萃取剂对铜及主要杂质铁的萃取行为,并进行了串级流动试验,考察了铜、铁的分离效果,确定了不影响黄金收率的最佳铜、铁萃取分离流程。

关键词: 铜, 铁, 萃取, 羟基壬基乙酰苯酮肟, 羟肟萃取剂

Abstract: Survey has been carried out to select a suitable hydroxyl oxime reagent to extract copper from a leaching solution of sulphating roasting calcine of gold containing sulphide ores.The behaviours of extraction and stripping of copper and impurities in leaching solution have been investigated both in bench scale and contra-current experiments in a mixer-setteler.A new extraction-electrowinning process has been suggested, which ensures an optimum copper recovery and purity,and paticularly,no harm for the cyanidation of gold and silver in the copper leaching residue.

Key words: copper, iron, extraction, hydroxy-nonylacetophenone oxime
