A study of mechanisms affecting molybdenite recovery in a bulk copper/molybdenum flotation circuit

A Molybdenum Flotation case study with about 6% of the molybdenum contained in the feed is present as an oxide form and about 90% of this is not recovered to the flotation concentrate. Recovery of molybdenum into the rougher concentrate varied between 90 to 95% at a concentrate grade of 2.5 to 3.7% molybdenum. The rougher concentrate can be upgraded to a marketable grade molybdenum …
