Andrada Mining has invested in TOMRA’s XRT sensor-based sorting technology for its expansion plans at the flagship Uis Mine in Namibia.
Andrada purchased TOMRA COM Tertiary XRT sorters, incorporating the latest OBTAIN™ software that leverages deep learning for single-particle precision in high-throughput particle sorting.
“TOMRA’s XRT sorters are a game-changer, combining high-tech sensors, powerful sorting valves and industry-leading software for exceptional reliability. With TOMRA’s OBTAIN™ imaging software, we can boost production output while maximising mineral recovery and ore quality, which is a win-win for efficiency and earnings,” Andrada Mining Chief Executive Officer Anthony Viljoen said.
Viljoen said the Uis Mine, an open-pit operation, holds the largest tin reserves in Namibia, with plans to increase concentrate production.
“Andrada’s expansion plans include the introduction of a pre-concentrating circuit of ore sorters aimed at increasing tin concentrate production from 1,500 to 2,600 tonnes per annum (tpa),” he said.
The newly acquired XRT sorters are expected to boost the tin content of the feed to the wet processing plant by 50%.
“The sorting technology includes a COM Tertiary XRT 1200 for coarse size fractions and two COM Tertiary XRT Fines sorters equipped with the high-resolution TS100C ejection module for smaller particle sizes. This module uses 90% less compressed air to eject particles, significantly reducing energy consumption and operating costs while delivering a high-quality product,” said TOMRA Mining Area Sales Manager for Southern Africa Helga van Lochem.
At the heart of this technology is TOMRA’s groundbreaking AI-powered OBTAIN™ software, launched earlier this year at the Mining Indaba exhibition.
Van Lochem said this software employs a Neuronal Network to accurately identify and sort particles, achieving unparalleled precision and reliability. It not only enhances sorter performance but also provides detailed data to optimise the mining process.
“We are excited about teaming up with Andrada Mining and helping them unlock value at their flagship Uis mine with our XRT sorters, the first to incorporate our OBTAIN™ Deep Learning feature unveiled just a few months ago. We will be at their side throughout the installation process and beyond, ensuring the sorters perform as required, meeting and even exceeding expectations,” he said.
TOMRA Mining boasts approximately 105,000 installations in over 100 markets worldwide and reported revenues of about 12 billion NOK in 2022.
Headquartered in Asker, Norway, TOMRA employs 5,000 people globally and is listed on the Oslo Stock Exchange. Andrada is an African tech-metals mining company with a portfolio of mining and exploration assets in Namibia and is dual-listed on the Namibian Stock Exchange
