WhatsApp: +86 18203695377Bauxite 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 18203695377Bauxite is the only raw material used in the production of alumina on a commercial scale in the United States. Although currently not economically competitive with bauxite, vast resources of clay are technically feasible sources of alumina. Other raw materials, such as alunite, anorthosite, coal wastes, and oil shales, offer additional
