bauxite mining method

  • Bauxite Mining in the Boké Region (Western Guinea):

    Bauxite mining does not require tunnels as digging gold mining or other mineral ores However, it still requires heavy digging equipment and generates tremendous dust that pollutes the surroundingThe bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors andMining and Refining – ProcessThe Bayer process, still economically the most feasible method for extracting aluminum from bauxite ore, involves mining, dissolving the alumina at an elevated temperature, adding flocculants, precipitating pure gibbsite, and heating the gibbsite to 1,100 degrees Celsius to yield alumina by calcinationmethod of bauxite mining Table of ContentsHistory and Production Description of DepositArkansas DepositsHurricane Creek DepositCharacteristics of BauxiteDevelopmentSurfaceBauxite Mining Method 911metallurgistBauxite Mining in the Boké Region (Western Guine a): Method Used and I mpacts on Physical Environment European Journal of Sustainable Develop ment Research , 3(3), em0087 Bauxite Mining in the Boké Region (Western Guinea):
