The beneficiation process of molybdenum ore is mainly performed by flotation separation methods, and the recovered molybdenum mineral is molybdenite(MoS2).Sometimes in order to improve the quality of molybdenum concentrate and remove impurities, the concentrated molybdenite would be subjected to a further step of beneficiation processing.

Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected as froth whereas the hydrophilic ...
