Commerce Resources Corp. Updates Programs for the Upper Fir Tantalum-Niobium Project, Blue River, British Columbia
Highlights Mineralogical variability studies show that the composites tested achieved similar recoveries (i.e. both by weight and grades of niobium and tantalum) to the partially optimized rougher flotation process established during the previous phase 1 and 2 metallurgical programs. Over 90% of the composites tested achieved rougher recoveries which exceeded 96% tantalum and 92% niobium […]
