Working in closed circuit with a hydrocyclone cluster, the SAG mill will produce a final particle size P80 of 240μm. The cyclone underflow from the SAG mill will be fed to a rougher flotation circuit to produce a concentrate, which will then be thickened and taken to a small regrind mill to reduce the particle size from P80 to 50μm.

Ball mill media optimization - Metcom Tech

mill speed are used to calculate the energy input. The specific energy input (E, in kWh/t) is the energy input divided by the mill solids load. The energy specific cumulative grinding rate (k) at each particle size is then calculated from the test feed and product size distributions using the first order disappearance rate equation (Equation 4).

Why use Different Size Balls in a Mill

Jul 03, 2017  The formula required that the largest ball size and the size to be rejected should be determined, and after that the other sizes were set. Stress was laid on the coarsest size, and to facilitate the use of the formula many writers have made their contribution by reporting ratio of coarsest particle size to the optimum ball size.

Ore processing – Waihi Gold

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.
