Molybdenum sulfide mineral and its floatability

There are about 30 kinds of molybdenum ore discovered in nature, including sulfide minerals, oxidized minerals, molybdates and other salts, but mainly molybdenum ore in the sulfide of molybdenum.

Molybdenite MoS ₂ containing Mo59.94%, S 40.06%, tungsten, rhenium, molybdenum and the like are common isomorphous substitution element, which is the most important rhenium molybdenite isomorphous mixed thereof, rhenium is the only The parasitic mineral is the raw material for the production of strontium.

Molybdenite oxidation at low temperatures to form a water-soluble surface oxide MoO _2.5; high temperature oxide forming a water-insoluble surface oxide MoO _3, it can reduce the brightness of the copper ore flotation, with a KOH solution Washing can remove the effect of such oxides on floatability.

Molybdenite due to its layered structure, having a good natural floatability, nonpolar hydrocarbon oils such as kerosene, diesel fuel and lubricants, foaming agents can be added only even float. In order to enhance the action of the hydrocarbon oil collector , it can be emulsified. The emulsification method is mechanically strong stirring, using ultrasonic waves and additives. Sulfur monoglyceride developed in China, called "Xintex" abroad is an emulsifier, which has both foaming and collecting properties, and can enhance the infiltration and collection of hydrocarbon oil collectors on the surface of molybdenite. Ability to improve its floatability. Inhibitors commonly used dextrin, medium regulators widely used water glass, sodium carbonate and caustic soda.
