Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...

Investigation of sediment control factors in river channels a catchment can play very important role the sustainable management that catchment. For this purpose, Ardak was selected, on which reservoir dam constructed for drinking and agricultural purposes large city Mashhad northeastern Iran. Then 57 samples were collected from surface to depth 30 cm along four rivers: A (14), B (23), C (13), D...

the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

Transportation costs are a significant part of capital and operating costs of large open pit mines. Cost efficiency and high reliability of in pit crushing and conveying systems compared to conventional truck-shovel system makes it more appealing to be utilized in modern mining activities. In this paper the suitable location of an in pit crusher is investigated as a single hub location problem....

Iran’s Sarcheshmeh copper industries with an annual production of 120,000 tones are the biggest of it’s kind in South Asia. The main method of production is pyrometallurgical matte making in two reverberatory furnaces which use direct–bond magnesite-chromite refractories supplied by German and Austrian companies. Following a recent major overhaul, bricks in contact with slag, matte and furnace ...

Solvent extraction of copper from the copper leach solution obtained from the ammoniacal carbonate leaching of the Sarcheshmeh copper concentrate was carried out, and the performance of CP-150, LIX984N, and Kelex100 as well as the effects of different parameters involved were investigated. According to the results obtained, the extraction kinetics of all the three extractants was fast. High con...

Weathering and oxidation of sulphide minerals in mine wastes release toxic elements surrounding environments. As an alternative to traditional sampling chemical analysis methods, the capability proximal remote sensing techniques was investigated this study predict Chromium (Cr) concentration 120 soil samples collected from a dumpsite Sarcheshmeh copper mine, Iran. The samples’ mineralogy Cr wer...

in recent years, the study of soil contamination problems surrounding the mines and smelting plants has attracted the serious attention of the environmental experts. in iran, due to the mining and mine development, the study of environmental problems seems to be obligatory. the main point of this research is the implications of the statistical and geostatistical studies to evaluate and prepare ...

soils around mining sites play a significant role in the transport and control of heavy metals in the environment. therefore, understanding the adsorption properties of soil is essential in solving pollution problems. the objective of this paper was to study zn(ii) adsorption onto sarcheshmeh copper mine soils. the adsorption isotherms of zn(ii) were studied. the langmuir isotherm indicated an ...

Liner design has become an increasingly more important tool for the AG/SAG mill performance optimization. The Sarcheshmeh copper complex concentration plant uses a SAG mill lined with 48 rows of Hi-Low type liners. Because of breakage of Low type liners and cold welding, the liner replacement task of Low with new Hi type liners has become very difficult and time-consuming. With the objective of...
