Molybdenum mining in the United States - Wikipedia

Both copper sulfides and molydenite are separated from the gangue by froth flotation. To separate the molybdenite from the copper sulfides, the copper/molybdenum concentrate is run through a molybdenite recovery flotation circuit, in which chemicals are added to "depress" the copper, meaning to prevent the copper sulfide minerals .

The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.
