Sedimentation is widely used in industry, from recycling to reuse in the mining industry, where iron ore tailings are present in the sedimentation sludge. It aimed to analyze the pH and concentration of ore tailings in the sedimentation, to compare the characteristics of the particles in the sedimentation. He applied the complete 2² batch factorial design, then analyzed the concentration of tailings particles in the sludge and in the clarified one. Calculations of the parameters related to sedimentation were performed. It designed a didactic sedimentation module, with a capacity of 1L. The best sedimentation was in acidic to neutral pH, by Scanning Electron Microscopy observed the influence of the particle diameter, providing even the possibility of optimization in water recovery processes, in the sedimentation of the mining industry.
