CONFIRMING TEST. An initial confirming test was conducted on the MC using test conditions from the P- 4080 work. A 2.0 kg MC sample was ball mill ground to a P80=191microns, then processed through a Knelson gravity concentrator. The Knelson concentrate was collected and hand panned for final Knelson concentrate. The hand panned tailings were combined with the Knelson gravity tailings and an 8 minute bulk sulfide flotation test was performed using Cytec A-208 and PAX (potassium amyl xanthate) at dosages of 0.02 lb/ton, each. MIBC frother was added at a dosage of 0.012 lb/t ore. Result show that 82% of the total gold was recovered into the combined Knelson + 8 minute rougher flotation concentrates, that assayed 4.2 opt. This compares, from the previous work, of a gold recovery (from 2 tests) of 81% and gold grade of 2.8 opt at a P80=186 microns. A summary of the test results is presented in the following table.
