  • The Chemistry and Processing of Jamaican Bauxite

    MiningDissolution of The Alumina at Elevated TemperaturesProduction FiguresThe surface occurrence of the ore (usually less than 100 feet)makes the deposits suitable for mining by simple opencastmethods. Due to the soft, earthy nature of the ore, no drillingor blasting is generally required. Deposits are located in areas varying from gentle undulatingto rugged, hilly terrain involving major capital expenditures inestablishing a system of ore transportation.See more on wwwchem.uwimona.edu.jm
