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, involved rock which contri only whenes the sterling(prenominal) towards the wargon of the divisor, aluminum. There atomic number 18 however respective(a) igneous rocks which consider at high slow-wittednesss of aluminium oxide but bauxite is financially more(prenominal) businesslike out-of-pocket to it universe 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 hematite and goethite, the clay mineral kaolinite (Al2Si2O5(OH)4) as considerably as low-toned amounts of Anatase which are a give of te dioxide. The largest Bauxite location in Australia is in Weipa, Queensland and is considered as the pisolitic-nodular approach cover type (1). This is due to the bauxite being in the get up of small, travel masses know as bauxite pisolites (1). The mental straination of Bauxite in Weipa was a combination of weathering as well as erosion. It begins with the unvaried hurry and drying of the top a couple of(prenominal) metres of the primer surface, a form of weathering. This causes a decrease in easily soluble pieces 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 heterogeneous other insoluble ?imperfections?.

This forms a acres surface cognize as laterite (1). Also, due to Weipa having much(prenominal) a flat ground surface erosion by both wind and piddle occurred easily without the disturbance of obstacles (mountains, assorted land formations). As a result, a lot of the ground surface, including bauxite pebbles, would have been transported into the adjacent disconnection of Carpentaria where the formation of bauxite will play once more. Such types of bauxite alike to the Weipa kind are overly found in countries such(prenominal) as... If you want to get a full essay, order it on our website: Ordercustompaper.com
