a high percentage of world copper production is obtained from porphyry copper reserves, these reserves are characterized by: very high tonnage, greater horizontal dimensions than vertical, association with stock like intrusion masses, dispersed minerals in the porphyry mass and in its neighbor rocks, intense sericitization and inplace silicification. the porphyry coppers are concentrated by flo...

sarcheshmeh porphyry copper deposit is located 65 km southwest of rafsanjan in kerman province. the sarcheshmeh deposit belongs to the southeastern part of urumieh-dokhtar magmatic assemblage (i.e., dehaj-sarduyeh zone). intrusion of sarcheshmeh granodiorite stock in faulted and thrusted early-tertiary volcano-sedimentary deposits, led to mineralization in miocene. in this research, the mass ch...

In the Buchim porphyry copper deposit, we determined several representative rare mineral phases, comprising metals from gold-palladium group as well those bismuth-selenium (Cu-Bi-Se-Te-As) group. The phases are represented by new in bismuthinite, galenobismutite, krupkaite, friedrichite, emplectite, laitakarite and native bismuth of gold-palladium, including gold palladium with their elemental ...

Mineral resource classification is an important step in mineral exploration and mining engineering. In this study, copper molybdenum resources were classified using a combination of the Turning Bands Simulation (TBSIM) Concentration–Volume (C–V) fractal model based on Conditional Coefficient Variation (CCV) for Cu realizations Masjed Daghi porphyry deposit, NW Iran. research, 100 scenarios loca...
