引言众所周知,毒砂中含有金和银。为了回收毒砂中的金和银,提出了各种各样的处理方法。但是,近年来从这种矿石以及别的物料中回收金银的研究日益增多。其原因一方面是在这段时间里,金的价格上涨;另一方面适合于处理低品位矿石的新工艺不断出现。这些事实,使得在某些情况下,金矿石能很好地加以利用,而在另一些情况下,却使过去那些有利可图的作业,在现在看来已经是不经济的了。
Introduction As we all know, arsenopyrite contains gold and silver. In order to recover arsenopyrite gold and silver, a variety of treatments have been proposed. However, there has been increasing research on the recovery of gold and silver from such ores and other materials in recent years. The reason is that on the one hand, the price of gold rises during this period; on the other hand, new processes suitable for handling low-grade ores continue to emerge. These facts make it possible to make good use of gold ores under certain circumstances, while in other cases, the lucrative operations of the past may now seem uneconomical.
