矿浆电位是影响硫化矿物无捕收剂浮选的最重要参数,无捕收剂浮选需要有一个适宜的矿浆电位范围。不同的硫化矿物有不同的浮选电位范围,调控矿浆电位可以实现硫化矿物间无捕收剂浮选分离,这是一个新的研究方向。以黄铜矿、方铅矿、闪锌矿、黄铁矿和毒砂为例,讨论它们的无捕收剂浮选行为的基本规律,在此基础上,设计用无捕收剂浮选技术进行各类复杂硫化矿体系的浮选分离方案。 The pulp potential is the most important parameter that affects the flotation of sulfide minerals without collectors. There is a need for a suitable pulp potential range for collectorless flotation. Different sulfide minerals have different flotation potential range, the regulation of the pulp potential can be realized between the sulfide minerals without collector flotation separation, which is a new research direction. Taking chalcopyrite, galena, sphalerite, pyrite and arsenopyrite as examples, the basic rules of their collectorless flotation behavior are discussed. On the basis of this, a collectorless flotation technology Various types of complex sulfide ore flotation separation program.
