Bauxite mining in Jamaica disturbs approximately 63 ha of land annually, being mined by the open pit method using a variety of earth-moving equipment (Neufville 1993).Prior to mining, the land is cleared of all vegetation and roughly 30 cm of top-soil removed (Neufville 1993).However, the organic fraction in such soils is often much closer Environment. Jamaican bauxites occur as pocket or blanket deposits of red earthy material on the karst surface of the Tertiary White Limestones, mainly in the interior of the island. The contact between the bauxite and the limestone is sharp, with a strong colour contrast between the dark red bauxite and the white limestone.Environment Jamaica Bauxite Institute
