在铅鼓风炉熔炼过程中,生成一种副产物铁、铜和铅的硫化物(铜铅锍),通称铅冰铜,其中含铜为6～10％,经过富集熔炼后,可以达20％以上。一般炼铅厂缺乏吹炼冰铜的设备,不能处理。如果由炼铜厂处理,因富集后含铅仍高,用铜炉处理也有困难,而且影响炼铜工人的健康,有价金属(如铅锌等)的损失很大。在选矿和湿法冶金业飞跃发展的今天,硫酸铜的需用量日益增多。因此将铅冰铜制成硫酸铜,然后回收其中的铅锌及贵金属,是有现实意义的。本文所述,仅限于前一部分的试验。
In the lead blast furnace smelting process, a byproduct of iron, copper and lead sulfide (copper-lead-sulfonium), known as lead matte, which contains 6 to 10% copper, after enrichment melting, up to 20% the above. General lack of smelting smelting equipment, matte, can not handle. If processed by a copper smelter, because of the high lead content after enrichment, it is also difficult to treat with copper furnaces, and the health of copper smelters is affected. The loss of valuable metals (such as lead, zinc, etc.) is very large. In the leap development of beneficiation and hydrometallurgy industry today, the need for copper sulfate is increasing. Therefore, the lead-copper matte copper sulfate, and then the recovery of lead, zinc and precious metals, it is of practical significance. This article describes, only the first part of the test.
