摘　　要：针对某钴冶炼厂砷钴精矿高酸浸出渣含钴、金、银高的特点,进行了提取金、银并综合回收钴的试验研究。研究结果表明,金的浸出率可以达到98．31％,银的浸出可以达到94．6％;钴经过回收可制得各种钴产品。实现了钴渣综合回收的目的。The acid leaching residue of arsenic cobalt concentrate contains high content of cobalt, gold and silver in a cobalt smelting plant. An experimental research on extracting gold, silver and recovering cobalt from the residue is carried out. It is revealed that the extraction rate of gold and silver is 98.31% and 94.6%, and the recovered cobalt can be used to produce kinds of cobalt products.
