Andrada Mining is upgrading its Uis mine in Namibia with sensor-based sorting technology, aiming to increase tin concentrate production from 1,500 to 2,600 tons annually.
The integration utilizes the COM Tertiary XRT sorters technology from TOMRA – a Norwegian technology solutions provider – designated for the dry process segment of the plant. These sorters are expected to enhance the tin content of the feed to the wet processing plant by 50%. Specifically, a COM Tertiary XRT 1200 will handle the coarse size fractions, while two COM Tertiary XRT Fines sorters, equipped with a high-resolution ejection module, will cater to smaller particle sizes.
“TOMRA’s proven ability to adapt solutions for fast-growing companies like Andrada ensures a smooth and swift implementation process…,” said Andrada Mining CEO Anthony Viljoen. “With TOMRA’s OBTAIN™ imaging software, we can boost production output while maximizing mineral recovery and ore quality, which is a win-win for efficiency and earnings.”
The Uis mine serves as a cornerstone of Andrada Mining’s operations, representing one of the largest tin reserves in the country. In addition, the company is currently expanding its product line-up to include both lithium and tantalum.
