A process for the extraction of alumina from aluminum-containing silicates is disclosed. The process comprises acid leaching of the raw material, iron extraction, precipitation of the aluminum fraction as the aluminum chloride hexahydrate, removal of sodium chloride and calcination to alumina. The process can be made continuous with substantial regeneration

A documentary study on alumina extraction processes from materials other than high grade bauxite ores, has been carried out at the request of the B.R.G.M. mis-sion in Saudi Arabia. Processes which are applicable to alumino silicates and related materials (high silica, high iron bauxites), have been exclusively considered in this study.

10-12-2021· Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth’s crust. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also occur as compact minerals, as veins, and are also present in many types of metamorphic rock.

Aluminum. Aluminum is the most abundant metal element in the Earth’s crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.
