different samples have been prepared from different products in chadormalu iron ore concentrator plant: low intensity magnetite separators concentrate (magnetite concentrate), reverse flotation tail (final hematite concentrate), flotation concentrate (apatite concentrate), final tail (l.i.m.s. tail + reverse flotation concentrate+ apatite flotation tail). the samples were used for rare earth el...
oeeuring in the Sangan arca was fonned within two different rock groups· graitoids and skarns. Based on the new amphibole classification and nomenclature, the general fonnula of amphibols IS (AB2C,T,O"OH),. Amphibole of granitoids is a ferroedenite in which Si = 6.87 - 7.75, CaR> 1.5, (Na+K)A > 0.5 and Ti < 0.5. Skarn amphiboles are mostly developed within amphibole skarns and gamet-pyr...

Summer catchment basins surrounding the city of Tehran, due to their remoteness from atmospheric pollution and urban manifestations, is considered as a place for exploring and recreating for many people, and as a place for money making out of restaurants attracting many tourists for others. Sangan is taken into consideration as one of the most beautiful valleys in Northwest of Tehran. The summe...
Nowadays, shovels play an important role in production of open pit mines and their failures result in significant production loss and considerable increase in maintenance costs. Therefore, reliability and risk analysis can help to improve production, productivity and reduce production costs. In this study, reliability of electric cable shovel of Chadormalu iron ore mine in Iran was investigated...
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...
