The process developed in this research is innovative, since there are no other papers referring to the production of metallurgical-grade gibbsite concentrate. It can be applied in the processing of natural fine bauxite ores, as in the CBA′s Miraí beneficiation plant, or to recover available alumina from tailings, as shown in this paper.
the process. The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.
