ing was the main bauxite mining technique in use. Since then, however, the process has shifted to the more economical, safe and environmentally friendly surface mining, and today WIRTGEN surface miners extract of the ore. Since 2001, the WIRTGEN technology has proven its additional benefit to the growing bauxite mining industry in
Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina.
Bauxite is the only ore containing 2025 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.
