It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between and These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
WhatsApp: +86 18838072829Bauxite has also seen growing use as a proppant in recent years. Proppants are used in the hydraulic fracturing process to "prop" open rock fissures allowing natural gas or oil to flow out. Bauxite is sintered in a rotary kiln in order to harden the material so that it can withstand the extreme pressures it will be subjected to.
WhatsApp: +86 18838072829Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which ...
