CORRELATION BETWEEN SILICON DIOXIDE AND ALUMINUM-OXIDE CONTENTS OF BAUXITE SAMPLES

The structure of bauxite deposits of Seydisehir (Turkey) were investig ated by simple but effective statistical analysis. The results obtaine d under variable aluminium oxide contents were used to generate an emp irical relationship by plotting, at different scales, (A(1)/A(2)) vers us (S-1/S-2), where A(1) is the percent aluminium oxide, A(2) is the m ean percent aluminium oxide, S-1 is the percent silicon dioxide and S- 2 is the mean percent silicon dioxide. As a result of these trials, it was found that the use of logarithmic coordinates gave a straight lin e with the empirical equation for the system in question being: A(1) = 1.010 . A(2) . S-1(0.016). S-2(-0.016).
