بيت /Flotation Gangue Molybdenite
flotation circuit was able to remove entrained gangue particles from concentrates, and it positioned flotation as the process to recover valuable minerals from sulfide ores. From there, flotation has been "the most important and versatile industrial process for the separation and concentration of minerals" (6). Flotation

The mineral molybdenite is a naturally occuring molybdenum sulfide (MoS 2) and is the principal ore from which metallic molybdenum is obtained. Molybdenite commonly occurs as a minor component in ores containing other metallic sulfides and is recovered therefrom as a byproduct in the refining of copper ores by froth flotation.

True flotation of nonsulphide gangue (NSG) only occurs due to attachment to molybdenite; the very low Mo grade of the ore results in very low NSG R max values. As a comparison, copper porphyry ore may exhibit NSG R max of 4 to 8%. The molybdenite recovery was generally poor under the standard size conditions with P 80 of 210 microns and "m ...
