Metallurgy

Four drill core composites, representing different rock and ore types, and a bulk composite of all these samples were processed at Dawson Metallurgical Laboratories in Murray, Utah (UN-INGEOMINAS, 1984; von Guttenberg, 2008). Standard grinding and flotation tests were completed. A bulk copper-molybdenum flotation concentrate was processed to produce copper and molybdenum concentrates. The copper concentrate has a grade of 24.2% Cu with a recovery of 85.9% and the molybdenum concentrate has a grade of 55.14% Mo with a recovery of 82.7%. Both concentrates are clean with no deleterious elements.
