Annually, hundreds of thousands tons slags are involved in the reverberator and flash smelting as well converting operations Cu-Fe sulfide concentrates to produce matte Sar Cheshmeh copper smelter plant, Iran, disposed landfill cooled air. Due their relatively high average content (about 1.5 wt%), a mineral processing plant based on flotation process has recently been established Cu-sulfide con...
Keybarkuh is located about 70 Km southwest of Khaf city (Khorasan Razavi Province) in the northeast of the Lut block. Rock units in the area comprises of slate, phyllite, schist and recrystalized limestone with Paleozoic age that was intruded by granite to diorite as dikes and stocks of Cretaceous to Tertiary age. Based on magnetic susceptibility, intrusive bodies are oxidant and reducing which...
The mineralization index of Yeylaghe Gharachi, as part of Arasbaran metallogenic belt, is located about 25 km northwest of Ahar, East-Azarbaidjan Province, NW Iran. The host rocks of this index consist of composite intrusive rocks with lithologic compositions of granite, quartz monzonite, granodiorite and diorite of Oligocene and Oligo-Miocene age. The alteration zones in this area are mainly p...
The new mineral amgaite was discovered at the Khokhoyskoe gold deposit, 120 km W of Aldan town, Aldanskiy District, Sakha Republic (Yakutia), Eastern Siberia, Russia. Amgaite forms fine-grained colloform aggregates up to 0.05 mm across, and is often intimately intergrown with avicennite, unidentified carbonates antimonates Tl. Other associated minerals include gold, silver, acanthite, arsenopyr...
Abstract The Ari vent field (AVF) is an ultramafic-hosted seafloor massive sulfide (SMS) deposit in the middle part of Central Indian Ridge. In this paper, we describe detailed mineralogy and geochemistry hydrothermal samples from AVF, which can be classified into Fe–Cu- Cu-rich types based on major minerals. Sulfide mineralisation former type comprises: (1) stage I, early deposition magnetite,...
Zaveh copper mineralization is located SE of Torbat-e-Hydarieh in Khorasan Razavi Province, in Khaf-Kashmar-Bardaskan Metallogenic Zone. Geology of the area includes Jurassic and Cretaceous sedimentary rocks and Eocene andesitic to rhyodacitic volcanic rocks. Mineralization is structurally controled and occurred as vein-veilet form with east-west ternding and hosted by Jurassic silicate-cemente...
The sowthwest of Sorkh kuh prospecting area is located in 120 km SW of Birjand city, western Lut Block. Geology of this area comprising andesitic and basaltic volcanic rocks, which have intruded by intrusive rocks such as hornblende diorite, hornblende tonalite, and biotite monzonite caused extensively alteration and mineralization. Based on remote sensing, field survey, petrography, and XRD, m...
Shekaste Sabz area is located in eastern Iran, about 96 km north west of Birjand. Preliminary prospecting in the area using ASTER mineral mapping (SAM) detected propylitic, argillic and sericitic alteration which was confirmed by field observation. The area comprises outcrops of Paleocene to Eocene volcanics, which was intruded by intermediate subvolcanic bodies. The main alterations zones are ...
Sorkheh Dizaj apatite - iron oxide deposit is located in southeast of Zanjan, within the Tarom subzone of Western Alborz - Azarbaijan structural zone. The oldest units in the area are Eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciated tuff and lapilli tuff intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton of Late Eocene - Early Oligocene age. Th...
The Shalang vein-type polymetallic ore deposit is located about 10 km southwest of Kerman and 70 km northeast of Sirjan, and lies in the central part of the Dehaj-Sarduieh metallogenic belt. This deposit is hosted by dacitic and andesitic vitric and crystal tuffs along with andesitic-dacitic lava flows of Eocene age. The alteration zones related to this deposit are propylitic, intermediate argi...
