  • Aluminium Mineral Extraction Open Pit Surface Mining

    Aluminium Mineral Extraction Open Pit Surface Mining

    The process of electrolysis is carried out to extract aluminium from aluminium oxide alumina. This is performed with the help of a steel vessel coated by graphite. Since the melting point of alumina is very high, cryolite and fluorspar are added for the purpose of reducing it.

    Before 5000 bce people in Mesopotamia were making fine pottery from a clay that consisted largely of an aluminum compound, and almost 4,000 years ago Egyptians and Babylonians used aluminum compounds in various chemicals and medicines. Pliny refers to alumen, known now as alum, a compound of aluminum widely employed in the ancient and medieval world to fix dyes in textiles. By the 18th century, the earthy base alumina was recognized as the potential source of a metal.

    Aluminum remained a laboratory curiosity until a French scientist, Henri Sainte-Claire Deville, announced a major improvement in Whlers method, which permitted Whlers pinheads to coalesce into lumps the size of marbles. Devilles process became the foundation of the aluminum industry. Bars of aluminum, made at Javel Chemical Works and exhibited in 1855 at the Paris Exposition Universelle, introduced the new metal to the public.

    Although enough was then known about the properties of aluminum to indicate a promising future, the cost of the chemical process for producing the metal was too high to permit widespread use. But important improvements presently brought breakthroughs on two fronts first, the Deville process was improved and, second, the development of the dynamo made available a large power source for electrolysis, which proved highly successful in separating the metal from its compounds.

    Hall immediately recognized the value of his discovery. He applied July 9, 1886, for a U.S. patent and worked energetically at developing the process. Hroult, on the other hand, although he applied several months earlier for patents, apparently failed to grasp the significance of the process. He continued work on a second successful process that produced an aluminum-copper alloy. Conveniently, in 1888, an Austrian chemist, Karl Joseph Bayer, discovered an improved method for making pure alumina from low-silica bauxite ores.

    The Bayer Process, which is used by about 80 active plants worldwide, is the primary method of producing aluminum from bauxite. Bauxite ore is dissolved in sodium hydroxide, or lye, at a high temperature and pressure. Then, the alumina and bauxite ores are separated by washing out the waste red muds or sands from the alumina. Finally, hydrated alumina is crystallized and calcinated dried in a furnace to produce solid alumina.

    Naturally-occurring radioactivity in bauxite ores is concentrated during the refining process, creating TENORM in bauxite refining residuals. The most frequently-occurring radionuclides found in red muds or sands include uranium, thorium, radium and their decay products. There are an estimated three billion tons of bauxite residue at both active and legacy processing sites.

    Bauxite is used to produce alumina, which is then used to produce aluminum. Wastes can be generated at several points in the production process, including during the mining of the bauxite ore, and during the refinery production process. The refinery processes used to produce aluminum generates about 2 2.5 tons of solid waste for every 1 ton of aluminum produced. This includes a small amount of waste rock, waste muds and a small amount of other scrap and solid wastes. These wastes can contain TENORM.

    The red mud waste dries to a very fine, powdery solid and contains significant amounts of iron, aluminum, calciumand sodium. The types and concentrations of minerals present in the muds depend on the composition of the ore and processing conditions. In some plants, red muds are further processed to produce aluminum oxides.

    Red muds are caustic, and the United States does not currently approve any secondary use of the waste. The radioactivity content is only one of several concerns that pose a risk to the environment, as red muds also have a high salinity and pH. In some red mud samples, the EPA has identified elevated arsenic and chromium concentrations in some cases, arsenic levels were as high as 16,000 parts per billion ppb, and chromium, 374,000 ppb. In the United States, wastes are usually disposed in large impoundments that are lined with clay or synthetic liners.
