Bauxite Mining and Alumina Refining
Typical deposits range in thickness from 3 to 15 m. The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay content and has to be washed before processing.

The World's Leading Bauxite Producing Countries
Bauxite is a soft limonite iron ore rock with portions of its iron composition replaced by aluminum. Bauxite forms when silica leaches out from laterite soil. Bauxite does not exhibit any particular composition instead it is just an assortment of clay minerals, aluminum hydroxides, and hydrous aluminum oxides.

Assignment 1.docx
1.0 Background study This study is aimed to choose an appropriate plant location and design a layout for an alumina processing plant from bauxite extraction. Our targeted production of alumina is 400,000 tpa. In order to produce this much of alumina we have to choose the appropriate size of the plant.

Energy needed to produce aluminum
Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called ''smelting'' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.

mining process of bauxite
Bauxite Mining. Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments Soils formed under these conditions are termed laterites In Arkansas the aluminum enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite an intrusive igneous rock

Chapter 2. Production and Processing of Aluminum
The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of production steps from the bauxite mine through casting is given in Fig. 2.1.

How aluminium is produced
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.

mineralogy (high processing costs) than lateritic deposits. Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery. However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability.

Mining and Refining – Process
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

Mining and Refining – Process
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.
