The article describes Reza gold deposit of Ugur exploration area located in Geda- bek Ore District the Lesser Caucasus NW Azerbaijan. It is established that main mineralization consists hematite-barite-quartz-kaoline veins- veinlets and breccia, pyrite stock-stockverk quartz-sulfide veins. On orebody surface center secondary quartzites with vein-veinlets barite-hematite have occured over...

The electro-deposition of titanium from two different classes of ionic liquids has been studied. Gold ions in solution have been used as an additive in order to provide a stable nucleation site for titanium to deposit on via a co-deposition process. Despite evidence from previous literature, it was found that it was not possible to reduce titanium from the +4 state to titanium (0) due to proble...

Solok Selatan is already known as an area that has potential precious metal, Gold. Local mining scale can be found on site certain areas in Abai Region, especially the North, which was previously believed to exist presence of these minerals. Based consideration associated mineral associations gold, course other metals deserves further investigation such Copper (Cu), Silver (Ag), Lead (Pb), Zinc...

Lateral, single-crystalline silicon nanowires were synthesized using chemical vapor deposition catalyzed by gold nanoparticles deposited on one of the vertical {1 1 1} sidewalls of trenches etched in Si(0 1 1) substrates. Upon encountering the opposing sidewalls of the trenches, the lateral nanowires formed a mechanically strong connection. The bridging connection at the opposing sidewall was o...

The ore mineralogy of a new promising target the Aldan–Stanovoy gold province—the Spokoininsky cluster—is considered. Gold mineralization is represented by volumetric, nonlinear type, unconventional for region; it related to elements fold structures and reverse fault in enclosing metamorphic basement rocks. Vein-disseminated sulfide–(pyrite)–quartz ores build up deposit-like bodies beresites fr...

A new approach is described for the recovery of precious metals (PMs: Au, Pd and Ag) with >99% efficiency from aqueous solution utilising biogas produced during the aerobic growth of Klebsiella pneumoniae. Gold was recovered from electronic scrap leachate ( approximately 95%) by this method, with some selectivity against Cu. The recovered PM solids all contained metal and sulphur as determined ...

A Life Cycle Inventory (LCI) was assembled for gold production extending from the formation of gold-ore deposits through the production of semi-refined gold-silver bullion. Inputs traditionally considered in life cycle assessment (LCA) such as energy, materials, and capital were counted along with geologic inputs and labor. Emergy, rather than traditional LCA methods, was used to make inventory...
