Abstract: A method and a system for characterizing an elemental composition and a molecular composition of a material are provided. Laser-based IR spectroscopy measurements and LIBS measurements are performed at a same analysis spot on the material. The IR spectroscopy measurement data can be used to characterize the molecular composition of the material, whereas the LIBS data can be used to characterize the elemental composition of the material. 2D and 3D profiles of a sample of the material may be obtained based on this data.

Abstract: A system for the online sorting of ore samples based on mineralogy analysis includes a conveyor moving a stream of the ore samples along a conveying path, a LIBS module, a height measuring device, a focus controller and an airflow system. The LIBS module projects a LIBS laser beam along an optical path focused on an analysis spot of dimensions of the order of one or a few mineral components of the ore samples, and collects a returning LIBS light signal. The height measuring device and focus controller collaborate to adjust in real-time the focus of the LIBS laser beam to move the analysis spot perpendicularly to the conveyor according to a height of the ore samples crossing the optical path. The air flow system moves particles away from the optical path. A processing unit performs the mineralogy analysis of the ore sample based on the LIBS light signal.

Abstract: A method of quantifying at least one property of interest of an oil sands ore sample is provided using a laser-induced breakdown spectroscopy (LIBS) method. The property of interest may include bitumen content, water content, particle size information, cation exchange capacity, methylene blue index, mineralogical content (e.g., quartz, total clay, and clay components), amorphous material content, total ash content, and connate water parameter (e.g., conductivity, chloride content, or alkalinity).
