The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide, and then reducing to the metal. The main mining areas are in the USA, China, Chile and Peru. ... High = substitution not possible or very difficult. Medium = substitution is possible but there may be an economic and/or ...
The study was aimed to recover molybdenum minerals from molybdenum ore with a high content of carbon by flotation process. The material belonged to a kind of refractory molybdenum ore from which molybdenum minerals could not be extracted effectively using traditional beneficiation and metallurgy, because of their similar floatability between carbon minerals and molybdenite and complex intergrowth.
Molybdenum. Molybdenum (element #42, symbol Mo) is a metallic, lead-gray element, with a high melting point (4,730 degrees Fahrenheit). This is 2,000 degrees higher than the melting point of steel, and 1,000 degrees higher than the melting temperature of most rocks.

The use of molybdenum above 6 per cent, was patented, as was the use of vanadium with either tungsten or molybdenum in high-speed steel. So far as molybdenum was concerned, the manufacture of these steels was discontinued almost before the patents had been allowed.
Molybdenum is also used in electrodes, as a catalyst, and as a high-temperature lubricant. Molybdenum was discovered as a new element by Carl Wilhelm Scheele in 1778, and was isolated and named by Peter Jacob Hjelm in 1781. Biological Benefits.
