Multisourced metals enriched by magmatic-hydrothermal fluids in stratabound deposits of the Middle–Lower Yangtze River metallogenic belt, China
Stratabound deposits within late Carboniferous carbonate units in the Middle–Lower Yangtze River metallogenic belt are important copper producers in China. Hitherto, the genesis of these deposits has been debated, due to poor constraints regarding the timing and source of the mineralization. Proposed models include a late Carboniferous seafloor exhalative formation (SEDEX), or an Early Cretaceo...
متن کاملElectrodeposition of metals from supercritical fluids.
Electrodeposition is a widely used materials-deposition technology with a number of unique features, in particular, the efficient use of starting materials, conformal, and directed coating. The properties of the solvent medium for electrodeposition are critical to the technique's applicability. Supercritical fluids are unique solvents which give a wide range of advantages for chemistry in gener...
متن کاملDynamic properties of Lennard-Jones fluids and liquid metals.
The dependence of the dynamic properties of liquid metals and Lennard-Jones fluids on the characteristics of the interaction potentials is analyzed. Molecular-dynamics simulations of liquids in analogous conditions but assuming that their particles interact either through a Lennard-Jones or a liquid-metal potential were carried out. The Lennard-Jones potentials were chosen so that both the effe...
متن کاملChemical Fluid Deposition of Metals from Supercritical Fluids
Chemical Fluid Deposition (CFD) involves the chemical reduction of organometallic compounds in SCFs to yield high purity deposits.[4] Typically, the reaction is initiated upon the addition of H2 or other reducing agent. The advantages of CFD over conventional deposition techniques are a consequence of the unique properties of SCFs, which lie intermediate to those of liquids and gases. Supercrit...
متن کاملIdentification of the fungi absorbing heavy metals isolated from waste deposits of zinc factories
The disposed wastes of zinc industries contain large amounts of heavy metals such as Pb2+ and Cd2+. These elements are considered as hazardous elements to human beings and other organisms. This study aims at introducing the fungal isolates that evolved to be compatible with waste deposits during the time and can absorb Pb2+ and Cd2+ions. During the spring and autumn in 2011, eight samples of se...
