the recovery process of selenium from iranian sar-cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. the copper anode slimes are made up of those components of the anodes, which are not soluble in the electrolyte. they contain varying quantities of precious metals like gold, silver, selenium and tellurium. they are being extracted as a by product in the co...
a linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in sar-cheshmeh copper mine, kerman, iran. a single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. the generated vibrations were measur...

Investigation of parent magma evolution and origin chromites in Cheshmeh-Bid, ophiolite Neyriz, Fars
Achaemenothrombium dariusi Saboori, Wohltmann & Hakimitabar sp. nov. (Acari, Prostigmata: Trombidioidea) is described and illustrated from larvae ectoparasitic on Euxoafallax (Eversmann) (Lepidoptera: Noctuidae) from Sirch and Cheshmeh Bondar, Kerman province, Iran. It is the third species of this genus, which is recorded only from Iran. The status of this small family is discussed and a key to...
molybdenite occurs in five forms in the sar cheshmeh porphyry copper deposit, namely, (1)-veinlets with quartz-molybdenite, (2)-veinlets with quartz-molydenite that were filled with pyrite, (3)-veinlets with quartz-molybdenite-pyrite–chalcopyrite, (4)-molybdenite veinlets with very low quartz and (5)-disseminated molybdenite grains. because of their large size, the veinlet-related molybdenite g...
The investigated area is a part of Sabzevar ophiolite melang of North Eastern Iran which is important from two points of view, geology and its potential of Economic Mineral deposits. The main geological units in both Chah Yabu and Cheshmeh Palang areas are serpentinized peridotite, gabbro, diabasic dykes of Upper Cretaceous and Tertiary volcanic rocks which are mainly altered. Cheshmeh Palang a...
