the ball mills, the pulp is classified in hydro-cyclones, with the fine material going to the flotation circuit and the coarse material being sent back to the ball mills or to the SAG. The flotation circuit contains six (4) lines operating in parallel with six flotation cells and two other cleaner lines.

Ball mills are in closed circuit with hydrocyclones. A portion of the circulating load passes through jigs for gravimetric recovery of gold (Fig. 3). Flotation is conducted in three stages: flash, scavenger and cleaner for Au and sulfide recovery. The floatation tails are thickened and then sent to the main tailings pond.

Abstract Strain-gauge measurements from a large ball mill are presented. Stress ranges determined from these strain-gauge measurements are compared with calculated stress ranges from a finite element analysis of the mill. It is shown that liner stiffness effects can result in lower-than-expected stress ranges at inboard plate flanges in the mill shell. There is good …
