Andrada Mining has purchased TOMRA XRT sorters as part of its expansion plans at the flagship Uis Mine in Namibia. The sorters feature TOMRA’s latest innovation launched earlier this year at the Mining Indaba exhibition: the groundbreaking OBTAINsoftware that leverages Deep Learning to bring single-particle precision to high-throughput particle sorting.

Andrada Mining, the African technology metals mining company, owns the open-pit Uis tin mine, which represents one of the largest tin reserves in Namibia. It is in the course of implementing expansion plans at the mine, which include introducing a pre-concentrating circuit of ore sorters with the aim of increasing tin concentrate from 1,500 to 2,600 tpa. It has purchased TOMRA COM Tertiary XRT sorters for the ore sorting pre-concentration circuit in the dry process section of the plant, expecting to increase the tin content of the feed to the wet processing plant by 50%.

A COM Tertiary XRT 1200 will be dedicated to the coarse size fraction. For the small particle sizes, two COM Tertiary XRT Fines sorters are equipped with the high-resolution TS100C ejection module, which delivers high precision in high-capacity applications. The module uses 90% less compressed air to eject the particles, reducing energy consumption dramatically and consequently significantly cutting operating costs while delivering a high-quality product.

These XRT sorters feature TOMRA’s groundbreaking AI-powered OBTAIN™ software which leverages Deep Learning to deliver single-particle precision in high-throughput ore sorting – an industry first. It uses a Neuronal Network to identify the properties of each particle accurately and independently of the sorter’s capacity, achieving unparalleled precision and reliability in detection and ejection. In addition to enhancing the sorters’ performance, taking capacity, quality and recovery to a new level, OBTAIN™ will provide Andrada Mining with a wealth of detailed and accurate data, which will help them optimize the process with better-informed decision-making.

Anthony Viljoen, Chief Executive Officer at Andrada Mining, said: “Andrada Mining is proud to partner with TOMRA, a market leader in ore sorting technology. TOMRA’s proven ability to adapt solutions for fast-growing companies like Andrada ensures a smooth and swift implementation process. 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 maximizing mineral recovery and ore quality which is a win-win for efficiency and earnings.”

Helga van Lochem, Area Sales Manager for Southern Africa at TOMRA Mining concludes: “We are excited about teaming up with Andrada Mining and helping them unlock value at their flagship Uis mine 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.”
