银是人类历史上最早使用的金属之一。随着科学技术的发展,银在各个工业部门的用途不断扩大,用量也日益增多。至使矿产银的产量远不能满足目前的消费要求,所缺部分只能由再生银补充。据报导,八十年代初,世界各国再生银为二亿五千万盎司左右,占总消耗量的73％以上。因此,进行银的再生研究具有十分重要的意义。含银废触点是再生银的重要途径之一。比如,这些年来,世界银产量的15％
Silver is one of the first metals used in human history. With the development of science and technology, the use of silver in various industrial sectors has been constantly expanding and the amount used has also been increasing. To make the production of silver far can not meet the current consumption requirements, the lack of only by the regenerative silver supplement. It is reported that in the early 1980s, silver regenerated silver was around 250 million ounces worldwide, accounting for more than 73% of the total consumption. Therefore, the study of silver regeneration is of great significance. Silver scrap contact is an important way to regenerate silver. For example, over the years, 15% of the world’s silver production,
