Kvanefjeld Refinery Pilot Plant Yields Excellent Initial Results


First phase of refinery pilot plant successfully completed at Outotec's research laboratories in Finland
Pilot plant operated continuously for approximately 250 hours, utilising mineral concentrate generated by the concentrator pilot plant conducted in May, 2015
High rare earth extractions of approximately 95% achieved, comfortably exceeding Feasibility Study design assumptions of 77%, uranium extractions of approximately 85% achieved in line with Feasibility Study assumptions
Design parameters for thickening, reagent selection and filtration firmed up
Outputs from refinery pilot plant will feed into optimisation studies to further strengthen project economics
Next steps include conditioning of residues that contain rare earths, re-leach with mild hydrochloric acid, impurity removal, and generation of a hi-purity product
Kvanefjeld refinery pilot plant conducted in conjunction with, and partly funded by the EURARE program, which aims to increase rare earth raw materials supply to Europe
