How Is Bauxite Formed? |
Karst bauxite ores are largely formed in places like Europe and Jamaica by clay concentration as carbonate rocks like dolomite and limestone weather away to leave the clay and ores behind. Bauxite is usually stripmined, because it is typically found near the surface of the local terrain. As of 2010, 70 to 80 percent of the dry bauxite is then used to create aluminum....
