Mid-infrared reflectance spectroscopy and laser-induced breakdown spectroscopy are combined to provide the quantitative mineral composition of rocks. Measurement results for kaolinite are presented and a relative error of kaolinite abundance of 0.8 %
Evaluation of bitumen content in oil sands feedstock is important to control the extraction process and improve the recovery efficiency. Current standard techniques for bitumen determination in oil sands ore suffer whether from their time-consuming l
