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...

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...

-This paper presents an investigation of comminution mechanisms and microstructure development within simulated fault gouge. We sheared 4.0 mm thick layers of quartz sand between rough steel surfaces using a triaxial apparatus. The layers were sheared at constant effective normal stress of 100 MPa, under saturated drained conditions, and at 45 ° to the axis of cylindrical steel samples. Porosit...

acid mine drainage (amd) containing high concentrations of iron and sulphate, low ph and variableconcentrations of heavy metals leads to many environmental problems. the concentrations of cu and mnare high in the amd of the sarcheshmeh porphyry copper mine, kerman province, south of iran. in thisstudy, the bio-remediation of cu and mn ions from acid mine drainage was investigated using two nati...

With the aim of revealing effects low temperature on vibration impact comminution performance wheat bran, dynamic bran at different temperatures was simulated by using LS-DYNA. According to collision relationship between grinding medium and a three-component numerical calculation model established. The essence analyzed, solution method based LS-DYNA proposed. On this basis, finite element obtai...

The performance of a comminution and classification process depends on the design configuration each unit, plant, control physical properties incoming feed. Comminution processes should be designed to have stable efficient production over wide range conditions. However, demands from management, operational cost, investment, maintenance or any other related field can result in alterations that a...

Patients who sustain an acetabular fracture are a challenge to the orthopedic surgeon because of the inherent difficulty of the fracture and its treatment. Acetabular fractures in elderly patients add another level of complexity with additional co-morbidities associated with age such as osteoporotic bone, the fracture type and comminution, medical conditions, and insufficient bone stock to supp...
