Bauxite is also one ore that contains a heavy amount of aluminum. For this reason, it is called aluminum ore. Bauxite is a sedimentary rock. It contains different components such as silica, sand, iron oxides, and aluminum oxides which later give rise to aluminum. The color of bauxite is of different types, light pink, orange or reddish.

An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.

Bauxite is a high-aluminum-content rock. That is the main ore that aluminium is mined from. One of the most common elements on earth is bauxite. It contains almost 25 percent-30% alumina. In the belt around the equator, bauxite is commonly found. The primary aluminium bearing ore with an aluminium content of more than 35 to 40 percent is bauxite.

Bauxite ore is the world's primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions.

bauxite Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal.

As we've seen, the Ore of a metal is not pure metal that we can directly use. The ore has impurities, and the metal must be obtained from its compounds. The process of removing impurities from ores is known as Concentration / Enrichment . After the ore has been concentrated, the metal can be extracted from the ore.

Firstly, aluminium has to be removed from the Earth, by mining. This is relatively simple, given the abundance of Aluminium. However, Aluminium is always bounded to other elements, and exists as compounds, often containing oxygen and silicon. Thus, it is impossible to obtain a pure substance of aluminium through mining. Aluminium's ore is bauxite.

Ore Deposit: Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit. It may be of any shape and form but its size is of real importance. A small patch or layer of bauxite, say one meter thick and a kilometer long will not make an ore deposit.

First ores are crushed and grinded and then gauge or matrix is removed from the powdered ore. This is called concentration of ores. Ores of highly, moderately, and low reactive metals are 1 st concentrated. This step is common for ores of all types of metals. It is carried out by various methods depending upon the nature of the ore.

The mineral bauxite is the primary ore from which aluminum is extracted. It is very plentiful in the earth's crust and a very useful and versatile metal.
