Bauxite is an aluminum-rich sedimentary rock. It is the principal ore of aluminum. Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite 4. The major impurities are iron oxides and hydroxides Bauxite occurs mainly in tropical and subtropical areas. In 2000, Australia was the leading worldwide bauxite producer with a production share of 39%, followed by Guinea (13%), Bauxite an overview ScienceDirect Topics

Aluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite. Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals. Although some bauxite deposits are hard rock, most consist of relatively soft dirt that is easily dug from open-pitJamaica has large commercial deposits of mineral resources such as limestone (two-thirds of the island), bauxite, gypsum, marble, silica sand, and clays. The mining and processing of bauxite continues to be the major economic activity.

With a per capita gross domestic product of only $760 in 2000, Guyana is one of the poorest countries in the Western Hemisphere. The economy made dramatic progress after President Hoyte's 1989 economic recovery program (ERP). As a result of the ERP, Guyana's GDP increased 6% in 1991 following 15 years of decline.Bauxite residue, known as “red mud,” is a potential raw material for extracting rare-earth elements (REEs). The main REEs (Sc, Y, La, Ce, Nd, Nb, and Sm) from the raw bauxite are concentrated in RM after the Bayer leaching process. The earlier worldwide studies were focused on the scandium (Sc) extraction from RM by Selective Scandium (Sc) Extraction from Bauxite Residue (Red
