一、铂族金属的回收法亟待改进铂族金属的用途在不断扩大,但资源少价格高,所以它的再生利用在日本受到高度重视。铂族金属的主要回收技术有干法和湿法两类,干法为对含铂等废金属预处理后再加入铜、铅等金属进行高温冶炼以便从铜、铅的共生金属相中将铂族金属等抽提分离回收的方法。这种方法在日本广泛用于工业生产,由于它的回收率高和处理速度快,已成为回收技术的主流,其缺点是需设备规模大,能耗和成本
First, the recovery of platinum group metals Urgent need to be improved The use of platinum group metals is constantly expanding, but less expensive resources, so its recycling is highly valued in Japan. The main recovery technologies of PGMs include dry and wet methods. The dry method is to carry out high temperature smelting of metals such as copper and lead after the preconditioning of waste metals such as platinum, so as to separate the platinum from the symbiotic metal phases of copper and lead Ethnic metal extraction and recovery methods. This method is widely used in Japan for industrial production, and has become the mainstream of recovery technology because of its high recovery rate and fast processing speed. The disadvantage of this method is that it requires large-scale equipment, energy consumption and cost
