Molybdenite as a rhenium carrier : first results of a spectroscopic approach using synchrotron radiation [PDF]
, 2013 The chemical and physical properties of rhenium render it a highly demanded metal for advanced applications in important industrial fields. This very scarce element occurs mainly in ores of porphyry copper-molybdenum deposits associated with the ...

Fluid history from crystal cavities in rapakivi, Pyterlahti, southeastern Finland [PDF]
Bulletin of the Geological Society of Finland, 1987 The crystal cavities lined with quartz, feldspars, biotite, fluorite and a number of accessory phases occurring in the Haikonvuori pyterlite quarry in the Wiborg rapakivi massif were studied with mineralogical, petrographical and chemical methods ...

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2
Small, Volume 22, Issue 25, 4 May 2026.The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Selective Leaching of Molybdenum from Bulk Concentrate by Electro-Oxidation
Metals, 2021 This paper proposes selective leaching of molybdenum from Mo/Cu complex bulk concentrates in a 5 M NaCl solution using the electro-oxidation method. Here, the effects of several factors such as pH, pulp density, current density, and temperatures were ...

Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

Study on Process Mineralogy and Mineral Processing Technology of A Low Grade Copper-Molybdenum Ore
Kuangchan zonghe liyong, 2023 A copper-molybdenum ore in Qinghai contains 0.084% Mo and 0.067% Cu. Process mineralogical study shows that molybdenum in the ore mainly exists in the form of molybdenite, while copper in the form of chalcopyrite, chalcocite and bornite.

How the Neoproterozoic S-isotope record illuminates the genesis of vein gold systems: an example from the Dalradian Supergroup in Scotland [PDF]
, 2013 The genesis of quartz vein-hosted gold mineralization in the Neoproterozoic–early Palaeozoic Dalradian Supergroup of Scotland remains controversial. An extensive new dataset of S-isotope analyses from the Tyndrum area, together with correlation of the ...
