| dc.description.abstract |
Leaching kinetics for the removal of iron from a low grade gibbsitic bauxite with hydrochloric acid were studied. Temperature and acid concentration had strong influence on the removal of iron. Calcium removal was quantitative within a short period with dilute acid. The mechanism for the dissolution of iron followed first order equation, -ln(l - alpha) = kt, with an apparent activation energy of 81.0 kJ/mol. Using 4 M acid removal of more than 98% iron was achieved from hematite together with about 10% alumina from gibbsite phases of the ore. (C) 1999 Published by Elsevier Science B.V.
