The model consists of grinding and separation sections. For the modelling of the grinding operation, breakage rates of the particles are correlated with design parameters and material characteristics. Separation operation of verticalrollermill will be modelled by appliion of current models.
Grinding mill types. In a typical mine operation, a crusher sends large chunks of copper ore, up to 1ft diam., to a primary, or semiautogenous grinding mill (SAG), Figure 1, which reduces the
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 ore mined is concentrated. The milling of copper ores as practiced in the larger
Superior selectivity of minerals liberation in Titan M mill as compared to conventional ball mills (for example, copper oredressing with Titan VSI mill yields 17,6% copper concentrate with 82,6% extraction as compared to 14,5% and 76,1% obtained with a ball mill grinding, respectively).

Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.
