Molybdenite Flotation - Metallurgist & Mineral …
Cyanide Leach Circuit. The final molybdenite flotation concentrate passes through a Denver automatic sampler before entering a 9.1 m (30-ft) diameter thickener where it is thickened to approximately 50% solids. The thickener is fitted with a manual rake-lift and a froth ring around the perimeter.

Selective flotation of chalcopyrite and molybdenite …
In summary, the contact angle results indicate that H 2 O 2 oxidation treatment could selectively alter the surface hydrophobicity of chalcopyrite, and hence, it could be applied for the selective flotation of chalcopyrite and molybdenite.
A novel approach for preferential flotation recovery …
The bench-scale flotation results demonstrated that compared to other two flotation approaches, the preferential Mo flotation approach using a new non-thiol collector obtained a high recovery of molybdenite in a molybdenum circuit, while the tailing of molybdenum circuit was treated by a copper flotation circuit to obtain a high recovery of ...
INVESTIGATION OF EFFECTIVE PARAMETERS FOR MOLYBDENITE ...
molybdenite in the rougher/scavengers of the bulk Cu/Mo flotation circuit was consistently lower than that of copper sulphide. Moreover, reducing the flotation feed solids percent led to an increase in molybdenite recovery whereas copper flotation was relatively unaffected.
(PDF) Selective flotation separation of molybdenite …
All of the experimental results suggest that humic acids can be employed as a selective depressant for molybdenite during the flotation separation of molybdenite and talc under alkaline conditions, and the higher adsorption density of HA on molybdenite over talc …

A novel approach for preferential flotation recovery …
In 2004, the price of molybdenum increased 10-fold resulting in a renewed emphasis on production of this metal, including efforts to optimize its flotation recovery. Molybdenite recovery in the bulk flotation circuit is consistently lower than that of the copper sulphides as well as being far more variable.

8-9-2016 · Molybdenite particles were obtained by sieving a high grade (MoS 2 > 95%) flotation concentrate from a North American mine. The molybdenite particles were cleaned with n-propyl bromide >93% (Ensolv) five times to remove the oil collector and washed several times with ethanol.
1 Froth Flotation – Fundamental Principles
difficult to develop predictive models for froth flotation, although work is being done to develop simple models that can predict the performance of the circuit from easily-measurable parameters such as solids recovery and tailings solid content (Rao et al., 1995). 1.1 Performance Calculations
molybdenum flotation developing
The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide ...
