NEWFOUNDLAND – Vancouver-based Crosshair Exploration and Mining reports that acid leach tests on samples from its Central Mineral Belt (CMB) property resulted in vanadium recoveries as high as 93.4%.
Approximately 70 kg of core samples from hole ML-182 were submitted to SGS Mineral Services Vancouver for preliminary metallurgical tests including acid leaching, caustic leaching and salt roast leaching. Sixteen of the samples were composited to provide one sample with a head grade of 0.2% V2O5 and less than 0.01% U3O8.
Agitated acid leach tests yielded the best results with two samples recovering 92.6% and 93.4% vanadium. These tests were performed in agitated glass reaction kettles and carried out at approximately 30% solids at 80°C over a 48-hour period. Recoveries ranged from 13.4% to 93.4% and were found to be directly correlated with acid consumption.
Uranium was first discovered in the Central Mineral Belt in 1956. More details are available at www.CrosshairExploration.com.
