Bauxite In Weipa, Queensland Question: Perform research on an ore located in Queensland. Describe the processes involved in extracting and smelting.

Bauxite is a naturally occurring, diversified rock which contri only whenes the superlative towards the w ar of the divisor, aluminum. There argon however respective(a) igneous rocks which figure at high tightnesss of aluminium oxide but bauxite is financially much businesslike out-of-pocket to it cosmos far cheaper to extract the aluminium oxide. The champion minerals in bauxite are gibbsite (Al(OH)3), boehmite (AlO(OH)) and diaspore, which has the same composition as boehmite, but is denser and harder (7). There?s besides the presence of impurities. These whitethorn imply the iron oxides haematite and goethite, the clay mineral kaolinite (Al2Si2O5(OH)4) as considerably as menial amounts of Anatase which are a clay of te dioxide. The largest Bauxite location in Australia is in Weipa, Queensland and is considered as the pisolitic-nodular muster up cover type (1). This is due to the bauxite being in the pull in of small, travel masses cognise as bauxite pisolites (1). The diversityation of Bauxite in Weipa was a combination of weathering as well as erosion. It begins with the unvarying hurry and drying of the top hardly a(prenominal) metres of the prove surface, a form of weathering. This causes a decrease in easily soluble grammatical constituents much(prenominal) as Sodium and Calcium and as a result, there?s an increase in the concentration of the more insoluble element Aluminium along with disstandardized other insoluble ?imperfections?.

This forms a underfur surface know as laterite (1). Also, due to Weipa having such(prenominal)(prenominal) a flat ground surface erosion by both wind and water system occurred easily without the disturbance of obstacles (mountains, several(a) land formations). As a result, a lot of the ground surface, including bauxite pebbles, would have been transported into the adjacent disconnectedness of Carpentaria where the formation of bauxite will reprise once more. Such types of bauxite similar to the Weipa kind are too found in countries such as... If you want to get a full essay, order it on our website: Orderessay
