The Wushan Operation has been studied as a case study, particularly relevant to the copper-molybdenum separation circuit, in which efforts have made improve quality of molybdenum concentrate through diagnostic analysis. A key finding appearance coarser silicate minerals due their inadvertent activation flotation. suitable flotation conditions occurs, most likely, upstream bulk regarding usage n...

In this study, two auxiliary collectors (methyl naphthalene and naphthalene) of molybdenite the traditional collector (kerosene) were mixed for flotation, respectively. According to selection analysis collector, it was found that surface energy (γC= 44.50 mJ/m2) polycyclic aromatic hydrocarbons is very close (γS= 42.55 {100} surface. Therefore, can be physically adsorbed onto according principl...

The objective of this work was to study the effect muscovite and biotite on flotation chalcopyrite molybdenite in seawater, use sodium hexametaphosphate silicate improve copper molybdenum recoveries. impact inorganic dispersants settling properties resulting tailings also studied. It found that depress with depressing being stronger at pH 11 than 9. Sodium increased recoveries seawater. These r...

the possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. the results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. on the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...
