为了搞好一批国外进口含贵金属的非磁性金属废料的回收工作,我们进行了一些探索性实验。本文简单介绍实验过程。 (一)原料 被处理的原料是由国外某公司回收,经破碎、风选、磁选所得的含贵金属废料。原料的形状及组成均较复杂,其主要金属含量如表1,同时含有Sn、Pb、Ni、Al及微量的W、Si、Be、Mg、Cr等。 In order to do a good job of recycling a batch of foreign non-magnetic metal scrap containing precious metals, we conducted some exploratory experiments. This article briefly describes the experimental process. (A) Raw materials Processed raw materials are recovered from a foreign company, the crushed, air, magnetic separation of precious metals containing scrap. The shape and composition of raw materials are more complex, the main metal content as shown in Table 1, while containing Sn, Pb, Ni, Al and traces of W, Si, Be, Mg, Cr and so on.
