The lack of efficient processes to remove kaolinite - the greatest bearer of reactive silica - from bauxite narrows the use of many aluminum ores, such as marginal bauxites from Northeastern Para. The use of such ores would double the bauxite reserves in Brazil [3].

Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
