Gara-aghaj deposit located 36km northwest of urumieh is one of the titanium-phosphorous resources in Iran. The previous exploration studies indicated that there is 102Mt phosphorous ore deposit with average grading of 2.3% P2O5. In this research, the mineralogical studies of collected representative samples were performed by XRD, XRF, optical microscopy and SEM equipped by EDX. These studies in...
Detailed studies are done in order to investigate the ore body in Sangan mine. Analyses results showed very low amount of gold in mineralized zone, (max 32 ppb). It is indicated that there is a positive relation between Au, S and As whereas there was no special relation between Au and Cu. Therefore Au can not be found along with Cu sulfides such as chalcopyrite. The LREE elements are higher tha...
The research is aimed at study of the probable recovery iron from tailings Olcon mining company located in north-western Arctic zone Russia. Material composition a sample dump was analysed. authors have developed separation production technology to recover magnetite-hematite concentrate tailings. A processing flowsheet includes magnetic separation, milling and gravity concentration methods. pro...
The iron content of the ore used is crucial for the productivity and coke consumption rate in blast furnace pig iron production. Therefore, most iron ore deposits are processed in beneficiation plants to increase the iron content and remove impurities. In several comminution stages, the particle size of the ore is reduced to ensure that the iron oxides are physically liberated from the gangue. ...
Kalchoyeh copper deposit is located about 110 km east of Isfahan, in Central Iran, Urumieh- Bazman volcanoplutonic belt. Host rocks of this deposit are Eocene volcanic rocks and tuffs which are pyroxene andesitic lava and sandy and lithic tuffs. Sandy tuffs are the main host rocks of the deposit. Ore mineralization is taken place as veins and veinlets and quartz is the main gangue mineral. Hypo...
Abstract Magnetite is a common mineral in the Paleoproterozoic Stollberg Zn–Pb–Ag plus magnetite ore field (~6.6 Mt of production), which occurs 1.9 Ga metamorphosed felsic and mafic rocks. Mineralisation at consists bodies massive to semi-massive sphalerite–galena pyrrhotite (with subordinate pyrite, chalcopyrite, arsenopyrite magnetite) hosted by metavolcanic rocks skarn. sulfides, skarn, amp...
The Christmas copper mine is in the Banner mining district, Gila County, Arizona. It is 8 miles north of Winkelman and 22 miles south of Globe. The mine was opened in 1905; to the end of 1943 it had produced about 55,340,000 pounds of copper. In 1946 it was operated under lease. The ore is high-lime fluxing ore, required by the smelter at Hayden. The ore produced during 1942 averaged 2.16 perce...
Stockpiling and blending play a major role in maintaining the quantity and quality of the raw materials fed into processing plants, especially the cement, iron ore and steel making, and coal-fired power generation industries that usually require a much uniformed feed. Due to the variable nature of such materials, they even come from the same source and the produced ores or concentrates are seld...
Abstract Magnetite-based iron ore usually shows a high sticking tendency and poor reducibility in the fluidized bed because of its dense structure. To enhance fluidization reduction behaviors magnetite-based during hydrogen-induced reduction, effect prior oxidation treatment is investigated. The results show that untreated cannot be successfully tested temperature range between 600 °C 800 °C. A...
