EFFECT OF AUTOGENOUS AND BALL MILL GRINDING ON

T1 - EFFECT OF AUTOGENOUS AND BALL MILL GRINDING ON SULFIDE FLOTATION. N2 - The effects of grinding on the floatabilities of copper-nickel sulfides from Duluth gabbro were investigated. At the same mesh-of-grind copper, nickel, and cobalt recoveries were higher and residual sulfur in the tailings was lower with autogeneously ground pulps.

2008-12-16 · Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation, valuable minerals and gangue are separated by froth flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue [46].

Autogenous Grinding - Mining Fundamentals

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...

Copper conducts electricity. Only silver conducts electricity better than copper and traditionally costs 40 times the price of copper. Refining improves the conductivity of copper by lowering the electrical resistance. Resistance is like friction to electricity, and it causes energy to be lost as heat in poorly conducting wires.
