Abstract
Mechano-activation is often studied for various mineral industry applications, including in the alumina industry. Results found in the literature suggest potential alumina extraction improvement by mechano-activation, as well as an influence on reactive silica when lime is added during mechano-activation treatment. A bauxite sample was ground for 60 minutes in a laboratory scale attritor min, with and without lime, a treatment known to produce important changes due to mechano-activation. Analytical results for gibbsite and boehmite contents in treated bauxite differed significantly from original bauxite, whereas kaolinite (reactive silica) and quartz were much less affected. Desilication and digestion behaviours were investigated, showing considerable differences between original and attritor milled bauxites.
