Accordingly, this will generate the possibility of increasing the SAG mill throughput, without affecting the product particle size going to the secondary ball mills. For SAG mill design, this model could help by generating a correction factor over the power (kW) calculated in the usual way by multiplying the specific energy in kW h/t ...

Secondary Grinding Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½", (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The effect of scats on ballmill productivity was tested and it was concluded that scats may not have an adverse effect on productivity in secondary ballmills and composite mills, if large balls are present. The use of a trommel on the ballmill is suggested to solve related problems in the classification circuit.

The simulations indicated that more power than is available would be required for the primary ball mills at the current F 80 and throughput in order to meet the 40% 75 mm target. In the case of secondary ball mill, it appears that power was being lost without achieving a grind of 70%75 μm. Conclusion and recommendation

The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.
