Molybdenite Flotation Metallurgist Mineral Processing ...

A molybdenite selective flotation. It is well known that molybdenite is a mineral with natural floatability intrinsic hydrophobicity, and under conventional flotation technology is recovered together with copper sulfides.

Depressing effect of flocculants on molybdenite flotation.

The quality of recycled process water is an important issue in the flotation of Cu Mo ores. Processing of Cu Mo ores includes two steps: a bulk flotation where molybdenite is recovered together with Cu sulfides, and a subsequent selective flotation step where molybdenite is separated from depressed copper sulfides.

Flotation of molybdenite in the presence of microemulsified ...

for molybdenite flotation. This study is a preliminary investigation which used only pure molybdenite mineral as model systems to optimize the flotation using micro emulsified collector. Material and methods Materials Molybdenite sample used in this work was obtained from Jinxin Mines Ltd. Chifeng,

an off grade or low grade molybdenite ore material containing insoluble non sulfide gangue as well as other impurities is treated bybination of chemical and flotation steps to produce a molybdenite concentratemercially acceptable grade.

Review of the flotation of molybdenite. Part I: Surface ...

Mar 10, 2016 · Flotation of molybdenite is carried out with the use of hydrocarbons e.g., diesel oil, kerosene, etc.. From this one concludes that molybdenite must differ from other sulfides in that its surface is already hydrophobic Chander and Fuerstenau, 1972.

Collector depressant equilibria in the flotation of molybdenite

This dissertation presents the results of research on the flotation system potassium n amyl xanthate sodium sulfide molybdenite. The purposes of the research were 1 to determine the theoretical collector depressant equilibria conditions of this system necessary for the flotation or depression of molybdenite, 2 to ascertain the mechanism of adsorption or the collector potassium n amyl ...
