Weir Minerals increases capacity at OMV

Special Report: Owner vs contract miner

Aspasa to provide comprehensive training

This paper by the University of Johannesburg’s SM Rupprecht, reviews some of the better-known arguments about contract vs owner mining, and offers advice for establishing and managing the relationship between owners and contractors.

Looking at several solutions in terms of its plant, OMV has partnered with Weir Minerals Africa for an upgrade of its sand wash plant. With plant optimisation, the plant is getting 14 t/hour more in the cyclone underflow, which reports as a saleable product.

The Aggregate and Sand Producer’s Association of Southern Africa (Aspasa), is stepping up the amount of training on offer to members aimed at underpinning standards within the industry while simultaneously improving workforce skills.
