Molybdenum is removed as an FeMo precipitate by proper addition of ferric sulfate. Heavy metals are lowered by lime treatment. Solidliquid separation was achieved in both cases by flotation techniques. The Lectroclear electrocoagulationelectroflotation process was used to achieve the desired degree of metals removal.

10/09/2013 · Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various loions in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then ...

Pure molybdenum is extracted from ores by means of a flotation process. In this process the molybdenum is first obtained as the trioxide. Molybdenum trioxide is the main commercial product. It is the starting material for the production of molybdenumsteel and all other molybdenum compounds. Powdered molybdenum metal is produced by reduction

A rougher concentrate is together produced by two parallel rougher flotation banks. The rougher concentrate is processed and upgraded through a twostage flotation clean circuit. A bulk concentrate with both copper and molybdenum is thickened to separate the two minerals using differential flotation.

Large rotary rakes move the molybdenite concentrate to promote the chemical reaction. Desulfurisation systems such as sulfuric acid plants or lime scrubbers remove sulfur dioxide from the effluent roaster gases. The resulting roasted molybdenite concentrate typically contains a minimum of 57% molybdenum, and less than % sulfur.
