LIBS In-line Grade Scanner for Ore Sorting
The LIBS In-Line Grade Scanner is a quick and accurate scanner that can be used for primary in-line scanning for typical valuable materials (e.g. detect copper grade in copper ore) and forms the basis for Bulk Sorting at your mining site. Furthermore it can be used for secondary search for other valuable elements (e.g. Rare Earth Elements in tailings) or for penalty elements in ores (e.g. Arsenic in copper or gold ores). The equipment can also have applications off-line as a containerized closed loop principle, ideal for academic research, on-site R&D at the mine and as training or education tool.
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.
Together with Spectral Industries and TNO, Eijkelkamp SonicSampDrill developed the LIBS In-Line Grade Scanner for Ore Sorting.

After connecting the container with an outside 380/220 Volt power supply, the system is ready for use
Due to the solid construction, the system is less sensitive for the low frequency vibrations of an earthquake. The robust design enables reliable performance over a large temperature range.
