近来,在浮选中很注意用含醚结构的药剂。在浮选铜-钼矿时曾用乙基乙烯丁酯(-43)和二丁基缩醛(-4A),可以提高金属回收率。作者解释炔类化合物改善捕收剂性能的原因是由于它具有能完成与亲盐官能团同样作用特点的三键。
Recently, very attention in the flotation with ether-containing agents. In the flotation of copper - molybdenum ore used ethyl vinyl butyl (-43) and dibutyl acetal (-4A), can increase the metal recovery. The authors explain why acetylenic compounds improve collector performance because they have triple bonds that perform the same function as the salt-holding functional groups.
