一前言尽可能全部分离回收矿石中有用矿物,这从有效利用地下资源来说是很重要的。浮选法现在对各种旷物的分离回收,虽是最有效的方法之一,但在处理复杂硫化矿时,特别是铜-锌的浮选分离,现在还是最困难的问题。因此,本文准备在回顾铜锌分离的理论问题的基础上,研究其问题的所在。 The preamble states that the separation and recovery of the useful minerals from the ore as completely as possible is important from the efficient use of subterranean resources. Flotation method Now the separation and recovery of various excrements is one of the most effective methods. However, the flotation separation of copper and zinc, especially copper and zinc, is still the most difficult issue when dealing with complex sulfide ores. Therefore, this article is ready to review the theoretical problems of copper and zinc separation, based on the study of the problem.
