Bauxite and iron ore are two such types that are found naturally on earth. Bauxite is also known as aluminum ore and contains aluminum bearing minerals. Iron ore is a type of rock from which we can extract iron. The main difference between bauxite and iron ore is that bauxite is a source of aluminum whereas iron ore is a source of iron.

Note that the aggregate crushing value of the bauxite aggregate (8.0%) is much smaller than that of the granite aggregate (32.7%), which is consistent with that reported in Ref. [1]. For coarse aggregate, a higher aggregate crushing value generally corresponds to a lower compressive strength (Fig. 1). It is thus reasonable to assume …

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%.
