Copper Ore Processing Methods

Copper Ore Processing Methods The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper oreby mill operating parameters It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters Mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study It is hoped that the analysis of theTHE EFFECT OF BALL MILL OPERATING PARAMETERS ONThe pulp density is an important parameter which influences the grinding efficiency In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind Optimization of mill performance by using online ball and pulp measurements J o u r n a l P a p e rOptimization of mill performance by using
