A plant media sizing methodology, and industrial case studies, are provided. This work is ongoing. However, a number of key observations and conclusions can be made at this time. Size by size cumulative energy specific grinding rates can be used to characterize mill grinding performance and changes in performance, as a function of media sizing.
It is also suitable for the wet grinding process in highvelocity conditions. It provides a better size distribution. It also offers better wear resistance and more delicate internal crystal structure compared to any other finishing media. As a result, zirconia balls are a credible alternative to stainless steel media.

When it comes to productivity at remote mine sites, highly reliable and robust grinding equipment is key. Where SAG mills were prevalent in the past, the availability of smart variablespeed drive systems make HPGRs a competitive alternative to provide highthroughput and an energy efficient grinding process.
fractions. The long residence time of the gold within the grinding circuit can cause some of the GRG to become nongravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).
