Best Moly Collector Addition Point in Flotation | Grinding or Conditioning
Where is Molybdenum best collected by its collector, Grinding or Conditioning? The protocols of the testwork were done such that a comparison could be made between adding the Moly collector at the milling stage versus the conditioning stage. As shown, the proper addition point for the Moly collector is at the grinding stage. The Moly recovery improvement is 5 and 6.8% for the
Effect pH on Moly Rougher Recovery by Flotation
pH was varied in the moly flotation in roughers while attempting to maintain a eH in the low -500 mV. The results of the test, shows that the best recoveries of moly are achieved at pH values of 9 and below. The copper recoveries appear to get activated at these low pH values, but the copper recovery is sufficiently low
Effect of pH on Bulk Flotation of Copper – Molybdenum
Graphic Conclusions of this particular set of flotation tests: Copper – Irrelevant of pH, with enough float time and reagents, you usually reach a terminal bulk rougher Cu recovery in the low 90s (Green Box) – pH 10.3 gives you that terminal recovery in less mass (9%), more selectively, at a higher Conc grade (2.5%) VS the rest. Moly –
Proven Cu Mo Separation Circuit Flowsheet
Here is a Proven Cu Mo Separation Circuit Flowsheet (by flotation) many will model after. It is used a Canada’s largest copper-molybdenum mine. It uses NaSH and Nitrogen.
Model Example of Copper-Moly Separation Circuit and Flowsheet
The copper-moly separation circuit was modelled using the test kinetics. The circuit was configured to include columns in every stage in order to minimize the amount of entrainment and to maximize the washing effect of the molybdenum concentrate. The circuit was designed with long retention times so that it could be operated with a slow pulling rate to allow the
