21 kilometres north of Stewart (Figure 2-IZ-l), on the east The Silbak Premier mine is in northwest British Columbia, side of the Salmon River Valley. The original discovery of a that from 1918 to 1953 produced 4.3 million tonnes of ore high-grade vein in 1910 culminated in an underground mine grading 14.6 grams gold and 304 grams silver per tonne from sulphide-bearing stockworkveins and brecciazones. Current open pit reserves are 5.9 million tonnes grading 80.23 grams per tonne silver and 2.16 grams per tonne gold (Randall,

Thermal Conductivity of Cu and Al-Water Nanofluids
Nanofluids are suspensions of nanoparticles in the base fluids, a new challenge for thermal sciences provided by nanotechnology. In this paper, the tested fluids are prepared by dispersing the Al and Cu into water at three different concentrations such as 500, 1000 and 2000 ppm. Thermal conductivities of these fluids are measured experimentally by thermal property analyzer i.e. KD2 Pro by using...
متن کاملMineralogy and Geochemistry Studies of the Sorkheh Sediment-hosted Stratiform Copper (SSC) Deposit, NW Iran
The Sorkheh deposit in northwestern Iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (SSC) mineralization. It consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish Miocene sandstone and shallow-water) that overlie a thick sequence of red beds (Miocene Upper Red Formation). The host gray be...
متن کاملAn Improvement in Thermal and Rheological Properties of Water-based Drilling Fluids Using Multiwall Carbon Nanotube (MWCNT)
Designing drilling fluids for drilling in deep gas reservoirs and geothermal wells is a major challenge. Cooling drilling fluids and preparing stable mud with high thermal conductivity are of great concern. Drilling nanofluids, i.e. a low fraction of carbon nanotube (CNT) well dispersed in mud, may enhance the mixture thermal conductivity compared to the base fluids. Thus, they are potentially ...
متن کاملبررسی کانی‌سازی، زمین‌شیمی و میانبا‌رهای سیال در رگه‌های کوارتز در ذخیره طلای مزرعه شادی (شمال‌شرق تبریز)
The Mazra'eh Shadi is located about 130 km northeast of Tabriz (NW Iran) in the Arasbaran metallogenic belt. The deposit occurs as a series of veins within the Eocene andesites. Mineralization shows epithermal system that controlled by fault distribution. Epithermal textures within the veins include comb, vaggy quartz, cockade, boxworke, plate calcite and breccia. Pyrite is the main ore mineral...
متن کاملExperimental Investigation on the Viscosity of Nanofluids
In this study, the effect off adding SiO2 nanoparticles on the viscosity of base fluid is investigated experimentally. Base fluids are chosen among common heat transfer fluids such as ethylene glycol, transformer oil and water. In addition different volume percentages of ethylene glycol in water are used as ethylene glycol-water solution. In every base fluid different volume fractions of SiO2 n...
متن کاملبررسی رفتار ژئوشیمیایی سنگ‌کل و شیمی‌کانی‌های فلدسپار و بیوتیت در پهنه‌ی برشی شرق قروه (کردستان)
The studied shear zone is located in E-Qorveh (Kurdistan). The rocks of this zone are granite and granodiorite in composition. In present paper, deformed rocks, protomylonites and mylonites, are investigated in Sangin-Abad, Koh-e-Gazgaz and Poloserkan areas. Petrographic studies show that evidence of tectonic activities are such as myrmekite, recrystallized and slide alkali feldspars, fractured...
