Milling technology advanced further with the introduction of rotary mills. The mola asinaria which dates back 200-300 BC was a basic rotary mill driven by blindfolded horses, donkeys or mules and used mainly to grind flour and corn. Sometimes it used human power and was driven by slaves. It had a horizontal axle attached to a shaft which was attached to a runner stone (the upper stone or the

The plant was expanded to 600 ktpa in 2007 by replacing three-stage crushing with one-stage crushing and SAG milling. The plant was further expanded to 940 ktpa in 2008 by removing bottlenecks from thickening, leaching and filtration sections. In 2010, mining started on the new southern pit to extract ore from an extension of the main deposit.

Platinum is produced in South Africa by Amplats,

By 1936, throughput had expanded to 18 000 tons of ore per month, and the oxidized ore was nearly exhausted. It became necessary to commission a flotation plant and to install a small blast furnace and converter unit for the production of platinum-rich copper-nickel matte, which would cost less than bulk concentrate to transport to the UK refinery.
