摘要
对菲律宾某复杂金精矿的金、银提取工艺进行了研究。其试验结果表明:两段焙烧—两段酸浸—添加碳酸氢铵氰化提取金、银工艺指标较好;在一定条件下,金、银浸出率可分别达到98.78%、97.57%。
Process study on extracting gold and silver from one complex gold concentrate from the Philippines with various processes is carried out .The results show that extraction rate of gold and silver were better in the process of two stages roasting-two stages acid leaching-adding ammonium bicarbonate cyanide .Under this condition , the extraction rate of gold and silver were respectively 98.78 %、97.57 %.
