unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as beneficiation, which include washing, wet screening and mechanical or manual sorting.,mining and refining process world aluminium,mining and refining process. the bayer process was invented and patented in 1887 by austrian scientist karl josef bayer. two to three tonnes of bauxite are required to produce one tonne of alumina. 90 of the global alumina supply of around 90 million tonnes is used in aluminium production. alumina refineries tend to be located close to bauxite mines and/or

Performance Simulation Of The Transportation Process Risk

Performance Simulation of the Transportation Process Risk

china imports a large quantity of bauxite each year. bauxite in fine particles with high moisture has a high risk of liquefaction during the maritime transportation process, which is harmful to the stability and safety of the carrier. to ensure safe shipping, it is necessary to pay attention to the effects of the operation of cargo, the shiprsquos maneuvering and the ocean environment,performance simulation of the transportation process,transportation process. the simulation of the process risk helps to develop measures to intervene with the cargo behavior to keep the risk to an acceptable level. this study examined the transportation process of a bauxite carrier using the markov chain method at di erent stages of loading, unberthing, departure and sea navigation.
