bauxite is the most important aluminum ore. this form of rock consists mostly of the minerals gibbsite al(oh) 3 , boehmite γ-alo(oh), and diaspore α-alo(oh), in a mixture that usually includes the two iron oxides goethite and hematite , and may include the clay mineral kaolinite , and small amounts of the titanium minerals anatase tio 2 , ilmenite , fetio 3 , and feotio 2 .
bauxite is found in the district of east godavari and west godavari. it is also found in the anantgiri plateau. moving onto the state of jharkhand the

bauxite is found in most countries, but the larger deposits occur in the tropics. major deposits of gravels mixed with sand were discovered in australia in the 1950s, and it became the world’s top producer of bauxite by the early 21st century. other top producers include china, indonesia, brazil, and india.
for the beneficiation of bauxite at the indian alutnini-um company ltd's mines at bagru hill (lohardaga). the variation in the silica and alumina content with screen size of the run-oj thine as well as bauxite sub-jected to primary crushing is evaluated. a scheme. for beneficiation by dry screening the crushed bauxite at the mines is described.
bauxite mining a cause of distress for the burha river. orsa’s resident wakil ahmed highlighted that due to mining, the perennial burha river, which originates from the bauxite-rich area of chhattisgarh, is also drying up.. the burha river after entering jharkhand flows from near the orsa village and then passes through the middle of the palamau tiger reserve (ptr) and is considered its
