Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller''s earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types. Major domestic markets for these clays are as

caliche. A term applied broadly in the Southwestern United States (esp. Arizona) to a reddishbrown to buff or white calcareous material of secondary accumulation; commonly found in layers on or near the surface of stony soils of arid and semiarid regions, but also occurring as a subsoil deposit in subhumid climates. It is composed largely of crusts of soluble calcium salts in addition to such ...

The bauxite is blasted loose and washed to remove any excess clay. Bayer Process The second step is known as the Bayer process, which involves a combination of a chemical extraction and a mechanical separation to extract alumina (the base from of aluminium) from the bauxite.
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
