selective grinding make - cwzc.pl
Abstract: Selective grinding of bauxite with ratio of Al2O3/SiO2 (A/S) 4.4 at ball mill were studied in order to investigate the effect of grinding media characteristics on selective grinding of bauxite. Results show that when diameter of ball media is Φ15mm, selective grinding effect is best and at this moment A/S of the product at -0.5+0 ...

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%.
