The bauxite was studied both raw and grounded in a digital ball mill with 20 mm Ø stainless steel balls at 150 r.p.m. The bauxite was first grounded for 24 h, and the fraction under 0.5 mm was further grounded for 3 h. The grounded bauxite was calcined at increasing temperatures and used for all the tests.
