Aluminium production starts with the raw material bauxite, a clay like soil type found in a belt around the equator. The bauxite is mined from a few meters below the ground. The bauxite is mined from a few meters below the ground.
Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called "bauxite residue", followed by a calcination step which removes the water content in the hydroxide.

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. The ore is acquired through environmentally responsible strip-mining operations.

production steps from the bauxite mine through casting is given in Fig. 2.1. 2.1.1 Bauxite mining Aluminum comprises approximately 8% of the earth's crust, making it second only to silicon (27.7%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silicates (clays).
The steps in aluminum smelting are described below: Alumina is dissolved in molten cryolite at 1,000 degrees C (1,832 degrees F). This may seem like an extraordinarily high temperature until you realize that the melting point of pure alumina is 2,054 degrees C (3,729 degrees F).

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888.
Depending on its source, aluminium scrap may contain a range of impurities. ... Scrap refining process can be generically described with the following steps: ... The transformation of scrap into recycled aluminium alloys requires approximately 5% of the energy input needed to produce primary ingot from bauxite. Depending on the impurities in ...
