For efficient exploitation of natural raw material deposits and high-quality processing, grading and sorting of the extracted raw materials is required. The LIBS In-Line Grade Scanner (LIGS) makes possible quick and accurate scanning of typical valuable minerals, such as copper ore. It is designed to form the basis for bulk sorting at your mining site. Other applications include analysing materials for valuable secondary elements (e.g. rare earth elements in tailings) or for penalty elements (e.g. arsenic in copper or gold ores). The primary application for LIGS is on-site ore grading, with the device installed above a conveyor belt sampling a (sub)stream of the material of interest. Secondary applications include off-line in closed loop for example for on-site R&D at the mine, for academic research, and as training or education tool. The closed loop solution is available as a containerised solution.
The system can be containerized and works as a closed loop principle, ideal for R&D and as a training and education tool.
The open set up can be used for bulk sorting, the principle is In-line grade scanning above a sub stream.
The LIBS In-Line Grade Scanner for Ore Sorting was developed in cooperation with Spectral Industries and TNO.
