Fluoride method of processing molybdenite concentrate

The rapid development of new branches of industry has demanded the design and application of new materials-heat resistant, corrosion-resistant, low-density alloys and ceramic materials on the basis of oxides, nitrides and carbides of molybdenum. Such materials are widely applied for intensification of processes in power engineering, metallurgy and chemistry. From all known minerals, molybdenum molybdenite (MoS₂) has the most essential industrial application. It is a mineral of black color outwardly very similar to graphite. The methods of processing molybdenite, used in industry, are many-stage, are difficult in hardware design because of low speeds of interaction reactions with reactants and high corrosion action of used media. Such processes result in air contamination of the production site and of the environment. In the authors´ opinion, a more progressive and perspective method of molybdenite processing is a fluoride one, based on molybdenite interaction with elementary fluorine
