Statistical processing of experimental data on filterability of slurries of a number of metallurgical enterprises in the CIS on filters of FPACM ( Larox PF ) type was carried out. Regression dependences of residual moisture content and volume of collected filtrate on characteristics of initial pulp and parameters of dewatering process for copper and zinc concentrates were obtained. The efficiency of pulp dewatering process at press filters is estimated and the ways of its further improvement are indicated. Optimal parameters of the combined filtration process for a number of hydrometallurgical pulps are determined and recommendations for improvement of its technical and economic efficiency are given.
