摘要

采用溶剂萃取法对从电子废料和其他废料中回收的贵金属进行回收精制，从粗金中提取纯金。这种溶剂萃取方法的优点是便于快速处理，从而减少了金在装置中停留时间过长的利息负担。因此，该方法也被用于铂和钯的精炼。技术创新使废料种类更加复杂和多样化，我们正在努力适应这一趋势。

An efficient recovery of gold and other noble metals from electronic and other scraps

Pure gold is extracted from crude gold by the solvent extraction method in the recovery and refining process for Noble metals recovered from electronic and other scraps. This solvent extraction method is advantageous in that it facilitates rapid processing, thereby reducing the interest burden of gold staying too long in the unit. Therefore, the method is also used in the refining of platinum and palladium. Technological innovation has created more complex and diversified types of scraps, and efforts are being made to accommodate ourselves to such a trend.
