Molybdenum: 5 Factors Driving Price In 2021 - Commodity.com

Jun 04, 2021· Molybdenum is a solid, shiny, silvery metallic element that is ductile and malleable. It does not occur naturally as a free metal, but usually in an ore known as molybdenite. Molybdenum has a very high melting point, which enables it to form strong, stable carbon compounds in alloys such as steel. As a result, it is an important industrial element.

Molybdenum Processing - IMOA

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.
