The company Etruscan Diamonds operates a mobile sorting system from CommodasUltrasort at Tirisano, its diamond mine near Ventersdorp in South Africa

A container is temporarily stationed at the Tirisano diamond mine near Ventersdorp in South Africa. This mobile on-site installation contains an optical sorting system from CommodasUltrasort. For example, it can find diamonds which elude traditional sorting technologies. Re-treating a recovery tailings dump is only worth doing if large amounts of material can be moved through a process in a short time. Optical sorting makes it possible to detect remaining diamonds on the basis of their transparency and selectively extract them at a very high throughput rate. In South Africa many diamond mines have such recovery tailings dumps containing low or non-luminescent diamonds which can be recovered profitably using CommodasUltrasort technology. This is a conspicuous advantage.
