How The Bauxite Mining Is Done And What MaKenyary Is Used

  • Nine Things To Know About The Aluminum Industry In Jamaica

    Bauxite, the world''s main source of aluminum, has been mined in five parishes in Jamaica for almost 70 years. Mining is an extractive practice, once the ore is removed it no longer exists and cannot replace itself, and so decade after decade the land is strip mined, ruined, discarded, and then bauxite has to be found somewhere else.
