The Yuleken porphyry Cu-Mo deposit located in the Chinese Altay-East Junggar, a section of Central Asian Orogenic Belt, world's largest Phanerozoic subduction-accretionary orogen, witnessed multistage tectonic-magmatic evolution and mineralization from arc to syn- post-collision environment over time span about 52 Ma. Four types molybdenite have been distinguished: (1) primary magmatic-hydrothe...

Since its discovery, graphene has been the object of study for several and manifold applications, ranging from photocatalysis to mechanics electronics materials. However, use pure in certain opto- microelectronic applications is sometimes limited because zero band gap. Among different methods widen gap, present work attention focused on so-called van der Waals composites (or heterostructures, o...

Separation of chalcopyrite from molybdenite is currently mainly carried out by flotation, but this process costly because the extensive use inhibitors. This study briefly describes a 7.0T/100CGC low-temperature superconducting magnetic separator and discusses its separation principle as well effect induction on molybdenite. A molybdenum (Mo) concentrate assaying 6.00% copper (Cu) 19.01% Mo was ...

leaching of molybdenite concentrate with hydrogen peroxide in sulfuric acid solution was investigated to determine the effects of reaction time, reaction temperature, h2o2 concentration, h2so4 concentration, pulp density and rotation speed on molybdenum extraction and molybdenite dissolution kinetics, using the taguchi method. from analysis of variance (anova) for molybdenum extraction, the mos...

Molybdenite is a common sulfide hosting many trace elements. Trace elements in molybdenite from individual deposits have been widely used to constrain the source and conditions of ore-forming fluids. However, relationship between element composition deposit types has not well investigated large dataset. Here, simple statistics partial least squares–discriminant analysis (PLS-DA) were determine ...

Porphyry-type deposits are the major sources of copper and molybdenum, flotation has been adopted to recover them separately. The conventional reagents used for depressing minerals, such as NaHS, Na2S, Nokes reagent, have potential emit toxic H2S gas when pulp pH was not properly controlled. Thus, in this study applicability microencapsulation (ME) using ferrous phosphate ions an alternative pr...

This study evaluates the effects of different additives such as silver ion, medium and energy sources on the efficiency of mixed moderate thermophilic bioleaching approach to extract Cu, Mo and Re from molybdenite concentrate containing 0.98% Cu, 1.56% Fe, 53.84% Mo, and 0.055% Re. Molybdenite was the major phase of Mo-bearing mineral and chalcopyrite, covellite and pyrite were distinguished as...
