Molybdenum Flotation

Molybdenum ore mainly includes molybdenite single ore, copper-molybdenum ore, molybdenum-containing polymetallic ore, etc. Flotation is the main method, sometimes combined with gravity and magnetic separation. Specifically, the molybdenum ore process should be selected according to the nature of the mineral.

• Molybdenite separation: Molybdenite is generally lamellar and easy to float. However, the content of molybdenum in molybdenum ore is very low, generally 0.01% to 0.4%. Two-stage regrinding of coarse concentrate and multiple flotation processes are adopted. High grade concentrate and less environmental pollution.
• Copper-molybdenum ore separation: Copper-molybdenum ore is one of the main sources of molybdenum. Copper-molybdenum deposits dominated by copper are usually porphyry-type copper deposits with low ore grades and fine grain size. Priority flotation and mixed flotation processes are mainly used. In priority flotation, the method of molybdenum first and then copper is more widely used. In mixed flotation, the method of separating molybdenum from copper-molybdenum concentrate is more commonly used.
• Separation of polymetallic molybdenum ores: Common tungsten-molybdenum-bismuth ores, quartz vein gold-molybdenum-lead-sulfur polymetallic ores. Generally, flotation is used to produce mixed rough concentrate, and then the mixed rough concentrate is separated according to the different properties of associated metals. It is commonly used in combination with magnetic separation, gravity separation and leaching.
