Role of Mineralogy and Geochemistry in the Beneficiation of Jajarm Bauxite from North East Iran: Comparison with some other Bauxite Deposits of the World
Two types of bauxite occur in the Jajarm Bauxite deposit, the first one is the hard bauxite and the other is the shaly bauxite or soft bauxite. The Al 2 O 3 content ranges from 30% to 60% and SiO 2 varies between 5% to 39%.The total tonnage is more than 22 million tons with a mean value of Al 2 O 3 content between 47% to 48% , SiO 2 around 10% and Fe 2 O 3 ranges between 6.95 to 27% . The Jajar...
متن کاملMineralogy and geochemistry of the Hajiabad manganese deposit, Hormozgan province
The Hajiabad manganese deposit is located about 40 km northeast of Hajiabad, Hormozgan Province. This deposit is structurally located in the southeastern border of the Sanandaj-Sirjan zone. The manganese mineralization in the study area is hosted by calcite-dolomitic marbles and mica schists of Devonian age, as layers, veins and massive ores. Based on microscopic investigations, the ores are do...

The Qara Sabalan manganese deposit belongs to the Qara Dagh-Sabalan metallogenic zone and is located in the eastern part of this zone (north of Meshginshahr). Geology of the area include volcanic (pyroclastic) rocks and the small outcrop of sub volcanic bodies (quartz-monzodiorite) with Eocene to Oligocene age. Mn deposit is hosted within the trachyandesite and tuff. Mn mineralization occurs as...
