Effects of solution pH and polyethylene oxide concentrations on molybdenite–molybdenite, molybdenite–kaolinite, and molybdenite–quartz interaction forces: AFM colloidal probe study

Separation and Purification Technology, 2022
Abstract Molybdenite (MoS2), a major resource for Mo, is often associated with some gangue minerals, such as kaolinite and quartz. The flotation separation of fine-grained molybdenite from gangue minerals is always difficult due to the low efficiency of capturing fine particle by bubbles and the heterogeneous agglomeration with gangue particles.

Bioleaching of molybdenite

Hydrometallurgy, 2008
Abstract Molybdenum was bioleached from molybdenite-containing mine waste samples and from high purity molybdenite in solutions amended with ferrous sulfate. Bioleaching of Mo occurred when solution Eh exceeded 750 mV to 800 mV (s.h.e.). The rate of bioleaching of high purity molybdenite increased with decreasing particle size, averaging 3.22 mg Mo/m

The effect of sodium hydrosulfide on molybdenite flotation as a depressant of copper sulfides

Minerals Engineering, 2020
Depressing copper sulfides using sodium hydrosulfide (NaHS) in the flotation of molybdenite is a common practice. However, the effect of NaHS on the flotation of molybdenite is not clear despite a number of studies.
