technology and dedicated service,’ according to the company. Koura also uses Tomra’s Color sorters at its San Luis Potosí processing plant and the Las Cuevas mine to remove calcium carbonate waste from its fluorspar feed using sensors. Tomra’s XRT sorters were installed in late 2024 and are due to begin operating imminently. The company expects them to reduce costs and environmental impact through minimised water and chemical consumption.
THE END USE IS IMPORTANT The sorting of fluorite is relative to the end use of the concentrate: MET Grade requires fluorspar to have a grade of 80-85%, with less than 5% silica and carbonates. Acid-grade fluorspar should have a grade of above 95% with less than 1% of carbonates and silica. A combination of sorting and flotation yields these grades, and in most applications, sorting or some type of preconcentration is a necessity. Most fluorspar mines in the world
are seeing their grades dropping below 40%. Tomra sorting can raise these grades to close to 80% in most applications with a considerable removal of carbonates and silica, and without the need to consume high volumes of water. Additionally, the benefits will be also realised during the flotation process, with lower costs due to the preconcentration. Fernando Romero-Lage, Latin
American sales manager from Tomra said: “We count on production-ready machines in our full-scale pilot plant testing warehouse, and we can precisely evaluate the suitability of sorting in any mining application. We apply different sensors to improve the grade without detriment to the recovery of the mineral: X-ray transmission, laser, optical, induction, and near-infrared. After testing for sensor suitability, we proceed with a full-scale test and we can guarantee the performance of the machine after these tests.”
TOMRA’S TECHNOLOGY IN DEPTH TOMRA XRT technology recognises
and separates fluorspar from carbonates and silica based on its specific atomic density. The sorters use a cutting-edge X-Ray module with Duoline sensor technology to measure spectral absorption information. TOMRA Sorting’s proprietary high-speed X-Ray processing unit uses the data to produce a detailed “density image” of the material. The result is a high level of purity in sorting materials, irrespective of size, the degree of moisture or surface pollution present. In addition to these higher X-ray detection capabilities, TOMRA XRT sorters benefit with the addition of Obtain, a deep learning technology that enables precise detection and classification of individual particles, even when clustered. It brings single-particle precision and higher-throughput sorting, according to the company.

Precision Drilling: from Mining to Geothermal Energy
Drilling down several thousands of meters requires high-tech tools and equipment. Equally crucial is the appropriate sensor technology, to keep to the exact drilling path for precise results. So are shock and heat resistance to prevent strong vibrations and high temperatures from skewing measurement outcomes while drilling through the rock strata.
For the geothermal energy industry, this is enabled by ASC inertial sensor technology. Our portfolio includes high-end JAE quartz-based JA-5 and JA-25 accelerometers particularly suitable for this purpose. In addition, MEMS-based ASC OS-series accelerometers conduct accurate, stable vibration analyses on machines like hydraulic deep drilling vibrators for soil inspection and preparation, to keep them running smoothly and prevent damage.
