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

Molybdenum Ore Processing by Flotation
May 05, 2016 This molybdenum flotation circuit, based on 250-500 tons per 24 hours is designed for low-grade molybdenum ore having high-grade streaks and with pyrite-quartz gangue.It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores. The basic ideas stressed in this moly flotation flowsheet are the importance of simplicity and the quick removal ...

Molybdenum Processing - IMOA
Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.

60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
