Africa, Botswana

Diamond

After nearly six years of effective XRT sorting operations at a diamond mine in Botswana, the XRT Sorters were on the brink of failure due to severe corrosion. In response, five XRT Sorters were replaced with new stainless steel XRT Sorters, along with ancillary upgrades. These replacement and upgrade efforts were carried out during three consecutive shutdowns and were accomplished promptly and within the allocated budget.

Capabilities
+ Retrofit sorters into existing operation
+ Expediting commissioning
