Part of bauxite which is used in Hydro Alunorte comes from MBP (Mineração Bauxita Paragominas) by pipeline to 240 Km away through seven cities. This mine provides bauxite to five production lines in the Hydro Alunorte. The objective of this work was to study the influence of the variables that influence the control cake moisture bauxite and solids in filtrate. We conducted an experimental plan based on statistical tool DOE. The parameters evaluated were: rotation speed, basin level and air pressure. The interaction between rotation speed, pressure and basin level was the condition of greater influence on the moisture. Alone the rotation was the most influential variable, followed by pressure. The experimental design in hyperbaric filtration process showed the factor of influence of each control parameter study and determined the strategy to achieve the goal of reducing the moisture content of bauxite.
