Recovery of high-grade copper from waste printed

2019-9-20  Copper concentrate with 79.06% grade corresponding with 71.47% recovery can be obtained when the grinding time is 3 min. It is established that grinding-assisted flotation is an alternative approach to recover high-grade copper from WPCBs.

Effect of grinding time on flotation recovery of

Copper smelting slags are hard materials. Therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. Copper smelting slags in the Bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm.
