copper molybdenum flotation process

Optimization of a Copper/Molybdenum Flotation Circuit by ...

Copper and molybdenum recoveries when occurring as sulfide minerals primarily rely on a process called flotation. This process was first patented by William Haynes in 1860 “who claimed that sulfides could be floated by oil and non-sulfide minerals could be removed by washing in a powdered ore” (6). The first commercial cell for a flotation
