·Bauxite is a sedimentary rock mineral that is the primary source of aluminum It is formed through the weathering of aluminum rich rocks in tropical and subtropical regions The name bauxite is derived from the French village of Les Baux where it was first discovered in 1821 by geologist Pierre Berthier Bauxite is typically found in
·Bauxite recoveries in modern washing plants is in the range of 60 80% however in some of the plants the recovery is found to be as low as 50% as they use simple vibrating screens in place of hydro cyclones The quality of input bauxite particularly silica content and targeted washed bauxite quality dictate the washed ore recovery
·The sequence characteristics of the bauxite ore body reflected that the ancient oxidation reduction conditions had varied between the concave and convex Ordovician limestone top interfaces It was found that due to controlled conditions of the paleo karst topography of the bases the formation characteristics of the bauxite ore
·As we know bauxite ore is very hard so it takes a longer time for crushing In the bauxite processing the Jaw Crusher is used in the coarse crushing and Impact Crusher is used in the secondary Cone Crusher is in fine crushing Usually according to the quarry conditions mobile crushing plants are also used in the bauxite quarrying
·The Gano karst bauxite deposit is located in the eastern Alborz Mountains 90 km NE of Semnan city northern Iran The layers and lenticular patches of bauxite are hosted in the Triassic karstified carbonate rocks interbedded with calcareous shale of the Elika Formation unconformably overlain by siliciclastics of the early Jurassic Shemshak
·Alumina is produced from bauxite which contains a mixture of various oxides such as aluminum Al iron Fe silicon Si and titanium Ti Bauxite can also be considered a source of several other valuable metals such as scandium Sc vanadium V and gallium Ga The composition and mineralogy of alumina determine their economic
·The Iranian karst bauxite deposits are mainly low grade aluminum ores The Jajarm deposit in the AMC with reserves of more than 19 Mt of bauxite ores at an average Al 2 O 3 /SiO 2 ratio of 43/14 Esmaeily et al 2010 and the Sar Faryab deposit in the ZSFB with reserves between 750 000 t and 3 Mt of bauxite ores grading 37 to 40 wt%
·The central part of the ZSFB comprises a series of small and medium sized karstic bauxite deposits Some of these deposits were recently reviewed by Zarasvandi et al 2010 Zarasvandi et al 2012 Zamanian et al 2016 and Ahmadnejad et al 2017 However despite the growing interest in karst type bauxite deposits as potential
·Iranian bauxite deposits which are part of the Irano Himalayan belt are spatially and temporally divided into five groups Ahmadnejad et al 2017 Table 1; Fig 1 1 Permian deposits in northwestern and northeastern Iran including for instance the Darzi Vali Khosravi et al 2017 and Jajarm Esmaeily et al 2010 bauxite deposits; 2 Permo
·The Kanirash bauxite deposit belongs to the Iran Himalayan karst type bauxite belt which is situated about 30 km southeast of Mahabad city northwestern Iran The bauxite ores are embedded by the
· Overview of Bauxite Ore As a residue of strong chemical weathering bauxite is mainly composed of Al oxyhydroxides Fe oxides/ oxyhydroxides and Ti oxides Khosravi et al restored the palaeogeographical locations of Iranian bauxite using a global plate tectonic model P ANALESIS model Based on this method they found that bauxite
·Opinion Karst bauxite deposits in northwestern Iran are part of the Irano Himalayan bauxite belt [1 2] These deposits are similar to the Mediterranean type karst bauxite deposits [3 5]
