Molybdenum Ore Processing by Flotation

How to separate copper & molybdenum; the problem. Molybdenum is found in small amounts in practically all low grade porphoritic copper ores. It is usually present as the sulphide, molybdenite, which is readily recovered in the copper flotation concentrate. Copper sulphide flotation concentrates may contain from 0.25 to 1.00% MoS2.

The Metal Profile for Molybdenum

Molybdenum produced as a by-product of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.

Molybdenum Processing - imoa.info

Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide. The resulting MoS 2 concentrate contains between 85% and 92% MoS 2. Further treatment by acid leaching can be used to dissolve impurities like copper and lead if necessary.

Molybdenum: Learn How To Trade It at Commodity.com

Although many minerals contain molybdenum, only molybdenite contains enough of the element to make commercial production viable. Molybdenite can either occur alone in an ore body or alongside sulfide minerals of other metals, mainly copper. A typical viable ore body of molybdenite might contain between 0.01 and 0.25% molybdenum.
