Aluminum sulfate can be made by reacting crushed bauxite ore with sulfuric acid,
according to the following equation:
AI203 + 3H2SO4 == Al2(S04)3 + 3H2O
The bauxite ore contains 55.4% by weight of aluminum oxide, the remainder being
impurities. The sulfuric acid solution contains 77.7% H2 S04, the restbeing water.
To produce crude aluminum sulfate containing 1798 Ib of pure aluminum
sulfate, 1080 lb of bauxite ore and 2510 Ib of sulfuric acid solution are used.
