Molybdenum Processing

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.

Patent US2079805 - Process for extracting molybdenum from .

I have discovered that it is possible to obtain a extraction of the molybdenum contained in wulfenite, without its being necessary to crush the ore to a fineness beyond 60 to 80 mesh (0.246 to 0.175 millimeter sieve opening), while at the same time the molybdate obtained is purer than that obtained by prior art methods'.

The Economic History of Leadville, Colorado

At one point the option was dropped because of the lack of a market for molybdenum and because there was no feasible method of processing the ore. Later the option was renewed after King had a flotation process for concentrating the ore, but it was not until 1918 that King's group exercised their option and paid Senter.
