Tailing filtration has as main equipment vertical plate filter press, which is an equipment whose operation and performance involves several engineering disciplines such as mechanics, fluid mechanics, electrical, electronics and metallurgy, with the sole aim of extracting the largest amount of water from entering tailings pulp. Therefore, by involving several disciplines, final humidity depends on many parameters related to the disciplines involved. Thus, to achieve mínimum humidity, it is necessary to find each discipline optimal parameters in which filter operates. For that reason, this thesis main objective is to optimize metallurgical parameters of tailings pulp, density and fines percentage, which must enter the filter to obtain minimum cake humidity. That is why a strategic test plan was designed to study the effects of these two tailings pulp parameters, density and fines percentage, on final cake humidity, eventually opting for a 32 factorial design as a tests plan and running it in three stages. First stage of tests had the purpose of collecting information from current operation, from which it tumed out that density and fines percentage with which filter plant was operated were 1476.7 kg/m3 and 50.2% respectively, obtaining 15.1 % as final cake humidity. Second stage had the purpose of executing the planned factorial design tests and collecting experimental data with which a complete statistical analysis was carried out, finding a mathematical model of final humidity based on the density and fines percentage, which it gave us as optimal operation density ranges from 1700 to 1750 kg/m3 and fines percentage range from 46.89% to 46.96%. Finally, third stage was aimed at verifying optimal values found, tests were carri ed out where it was possible to have 1705.3 kg/m3 as density and 47.6% as fines percentage, obtaining 13.5% as cake humidity. Ranges at 95% confidence means of cake humidity before and after optimizing are (15.01 %; 15.23%) and (13.27%; 13.69%) respectively, being statistically preven that cake humidity was reduced by 10.6%.
