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 کاملTargeting Limestone and Bauxite Deposits in Southern India by Spectral Unmixing of Hyperspectral Image Data
This paper presents a study about the potential of spectral unmixing of hyperspectral satellite image data for targeting and quantification of mineral content in limestone and bauxite rich areas in southern India. ASTER image (acquired in the VNIR and SWIR regions) has been used in conjunction with SRTM – DEM and field studies. A new approach of spectral unmixing of ASTER image data delineated ...
متن کاملMineralogy and geochemistry of major, trace and REE elements, Pirashkaft Bauxite Deposits, Mamasani, Fars Province
The Pirashkaft bauxite deposit is located in north of the Paskuhak anticline in the Fars Province. The bauxite deposit present between Sarvak and Gurpy Formations, and formed during the Late Turonian time as a consequent of the Laramid orogeny phase. According to the geological investigations, the Pirashkaft bauxite is Karstic type. The residual ore studied in the Pirashkaft can be classified ...

country to the economic activity existing in developed countries. Incidentally, my planning office has just finished a feasibility study for an area in the Amazon Basin where 500 families may be settled in 14,400 hectares (1 hectare = 10,000 square meters), with a loan of $16,000 (United States dollars) per family extending over a 10-year period. After 10 years each family will have paid the lo...
متن کاملLunar Pyroclastic Deposits and the Origin of the Moon 1
Debate over the origin and evolution of the Moon, and implications relative to the Earth, has remained lively and productive since the last human exploration of that small planet in 1972. More recently, issues related to the evolution of Mars, Venus and Mercury have received increasing attention from the planetary geology community and the public as many robotic missions have augmented the earl...
