Final Report Describing Flotation Testing on Master Cumpusile No. 1 (RES 2C-2, 3-1 and 3A-1) from the Resolution Project
A series of flotation tests had been conducted at DML on the three individual composites that comprise MC-1. The initial scope of that test work was to evaluate if:
- The individual composites could be processed using conventional flotation techniques.
- An acceptable copper concentrate could be produced.
As the test work progressed the scope of work expanded to evaluate the primary grind size, rougher pH and flotation reagent dosage. Cleaner test work was also conducted to evaluate regrind fineness, and reagent addition to maximize copper and moly grade and recovery.
