VXP2500 Stirred Mill optimisation at Casmyn Mining Turk Mine

CMP 2014

Abstract

The development of stirred milling technology has proven to be an enabling technology in fine grained metallic deposits. The increased grinding efficiency allows for the economic size reduction required to produce saleable concentrates. This improvement has opened the door to retreatment projects such as reprocessing of historic gold mine tailings.

Recently a VXP2500 stirred mill was installed at Casmyn Mining Zimbabwe Turk mine to allow the reprocessing of historic mine tailings. After commissioning, an extensive joint research project between Casmyn and FLSmidth Minerals was conducted to optimise the performance of the mill.

This paper outlines the challenges encountered in the optimisation program and the outcomes form the joint research project.
