摘要
为了提高有色金属的回收率,中矿再磨是行之有效的方法之一。在某铜矿铜精矿品位不低于现场指标的前提下,综合应用Zeta电位、红外光谱等手段对中矿选择性分级再磨工艺机理进行研究,选择性分级再磨工艺可以不断循序渐进的对有用矿物进行磨矿、分级、浮选,形成磨浮大循环、大闭路磨矿,同时在闭路循环过程中改变原矿的表面性质,增大有用矿物的可浮性,使选矿回收率从86.12%提高至89.48%。
The regrinding of middling is one of an effective methods to increase the recovery of non-ferrous metals.On the premise that grade of copper concentrate is not less than one obtained on the actual site in a copper plant,the mechanism of selective classification,regrinding and flotation of flotation middling（SCRFFM） was researched by means of Zeta potential analysis and infrared spectroscopy.In the process of SCRFFM,the useful minerals are grinded,classified and floated gradually and continuously,the big cycle of grinding-floating and a big grinding circuit can be formed,at the same time the SCRFFM can change the surface properties of the valuable minerals and increase their floatability,the copper recovery can be raised from 86.12% to 89.48%.
