The Kholodninskoe pyrite-polymetallic deposit (Baikal-Patom plateau, Russia) was discovered in 1968, but the questions of its genesis still remain controversial. It is assumed that explosive activity volcanic apparatuses southern part Baikal-Muya zone as well underwater exhalations scattered spreading back-arc basin could have most likely influenced geochemical features amagmatic deposits Bodai...

Supergene oxidation-leaching and secondary sulfide enrichment in the SarCheshmeh porphyry Cu-Mo deposit generated a supergene profile to depths of 20 to 80 meters with oxide ore reserve about 22 Mt. @1.08% Cu and sulfides ore [email protected]% Cu. Geochemical distribution and behavior of trace metals associated with Cu namely Mo, Au, and Ag in the supergene profile of the SarCheshmeh were po...

Specimens of geopolymeric concrete on basis waste iron ore enrichment Dashkesan’s deposit and bottom ash combustion domestic were obtained. Herewith ratio mixture to binder made up 80:20. At obtaining geoconcrete specimens the concentration in was variated limits 10-50%wt. Normality water solution alkali activator from 1N 8N. Maximal values absorption containing 10, 20, 30, 40 50%wt correspondi...

The Sullivan deposit of British Columbia, Canada represents an ancient submarine hydrothermal system that formed a giant Pb-Zn-Ag massive sulfide deposit. Tourmaline is abundant in the deposit and acts as a good tracer that may reveal the nature of the original hydrothermal fluids and ore-forming processes, due to its refractory characteristics. Concentrations of Zr, Hf, Nb, Ta, U and Th in tou...
