Studies on the Equilibrium Diagram of the System Nickel Sulfide-Copper Sulfide-Iron Sulfide (Part 1)
چکیده ندارد.
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
Sedimentary Copper mineralization has been observed in Monj and Jolany locations in Bavanat (Sanandaj – Sirjan metamorphic belt). According to current study, the host rocks for copper mineralization in this area are green sandstones, generally in subarkose and arkose groups. Age of these sandstones is middle Jurassic. Copper mineralization is observed in two forms, sulfides form including chalc...
the investigated area is located 30 km south of sabzevar in halakabad village. geological phenomenons in area follow a trend of nw-se. mineralization consists of metallic and non-metallic (kaolin) mineralization. disseminated and veinlet mineralization is generally associated with argillic alteration type. pyrite is the most widespread type of sulfide mineralization in halakabad occurrences. it...
this paper presents the new geochemical isotopes sr and nd, and the mineralization data for the south neyshabour volcanic rocks located in ne iran. based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. all the analyzed volcanic rocks display enrichment in light rare earth elements (lree) relative to th...
the darreh-zar porphyry copper deposit, located in the urumieh – dokhtar magmatic belt, lies about 10 km southeast of sar-cheshmeh porphyry copper deposit. the ore body with hydrothermally altered zones including potassic, chlorite-sericite, sericite, argillic and propylitic all related to the darreh-zar porphyry stock intruded the eocene volcanic rocks. pyrite, chalcopyrite, molybdenite, with ...
