The use of rare earth elements (REE) such as lanthanum (La), cerium (Ce), praseodymium (Pr) and neodymium (Nd) has increased widely during last few decades. Geologist Kimmo Kärenlampi from Oulu Mining School has been exploring the REE resources found at Otanmäki in central Finland in his doctoral thesis.
He’s been using the handheld X-MET8000 Expert Geo to screen the elemental composition of rock samples collected from exploration areas and samples from laboratory scale mining processing studies. The results of the screenings have been used to select the most interesting samples for further processing and analysis.
