这里引述了近年来国外发表的一些资料,对有关浮选药剂研究的几个问题,进行探讨。 一、硫化矿石的选择性捕收剂 硫化矿物之间的互相分离,是一个比较复杂的问题。在解决这个问题的过程中,寻求理想的捕收剂,以促使选择性较高的硫化矿物捕收剂不断出现,非离子型二价硫酯类捕收剂不断发展,说明了这种发展趋向。 酯类捕收剂,大多数具有较高的选择 Here quoted in recent years some of the information published abroad, research on the flotation of several issues to be explored. First, the selectivity of sulfide ore collector Sulfur minerals separated from each other, is a more complex issue. In the process of settling this issue, the search for the ideal collector to promote the emergence of more selective sulfide mineral collectors and the continuous development of non-ionic divalent thioester collectors illustrate this trend . Ester collectors, most have a higher choice
