- Abstract
A flowsheet was developed involving Cu-S bulk flotation from ore grading 0.39% Cu, 0.65 g/t Au, 7.20 g/t Ag, 5.22% S and 6.23% Fe, regrinding of the bulk concentrate and separation of Cu and S. Closed- circuit tests resulted in the production of a Cu concentrate grading 23. 39%, 21.6 g/t Au, 162 g/t Ag and 27.09% S, recovering 82.17% of Cu with 7. 78% of S as well as 45.53% of Au and 30.83% of Ag, and a S concentrate with a grade and recovery of 36.58% and 61.97%., A flowsheet was developed involving Cu-S bulk flotation from ore grading 0.39% Cu, 0.65 g/t Au, 7.20 g/t Ag, 5.22% S and 6.23% Fe, regrinding of the bulk concentrate and separation of Cu and S.
