Take example of molybdenite. The molecular formula of molybdenite is MoS2; it existed in original porphyry deposit. It accretes with pyrite, chalcopyrite, sphalerite, etc. The density of molybdenite is 4.7-5 t/m³, hardness is 1.0-1.5, loose density is 1.65. Main molybdenum originals are America, Canada, Chilly, Russia, etc. our country has a great molybdenum source, broad distributions, rich contain, great potential.
Crushing system of molybdenum is using Three sections + One closed circuit process, but some also use Two sections + One closed circuit.
Because the undressing molybdenum grade is low, embedded degree is fine, the features of molybdenum beneficiation process are periodicity grinding, more sections flotation concentration. In our country, some molybdenum concentrator’ s concentration is more than 9 times, the tailings of every section should be back to prior section to select again. In addition, take consider of beneficial group‘s comprehensive recovery and sand beneficiation process.
Main equipments include Jaw Crusher, Cone Crusher, Circular Vibrating Screen, Ball Mill, Spiral Classifier, Hydrocyclone or High Frequency Fine Screen, Flotation Machine, Thickener, Filter Machine, Dryer, etc. Zoneding Machine can provide crushing and screening equipment, grinding equipment, flotation equipment, thickener equipment which can meet the molybdenum beneficiation requests.
The molybdenum grade should be up to 45%, other impurity content is controlled accordance with National Quality standards. The basic beneficiation process of Molybdenite as follows:
The typical case of molybdenum beneficiation is Jinduicheng concentrator, Yangjiazhangzi concentrator in Liaoning province, concentrator of Lizhou, Henan.
We suggest making a small beneficiating trial to ensure the reasonability of process before ensuring process.
