The article considers new principles of flotation processes laboratory studies by means of multi-sensor ionometry systems. The experiments were conducted on the Tominskoye porphyritic copper-molybdenum deposit ore sample. A new principle of pulp electrochemical potential control by means of molybdenum electrode is substantiated experimentally and mathematically. Sulfide minerals effective flotation and depression ranges are determined. The advantages of new approach to pulp electrochemical potential control by means of molybdenum elec trode in contrast to conventionally used electrochemical potential control based on platinum electrode potential measurements are shown. A new principle of laboratory studies' results analysis by means of a neural network modeling method, permitting to reveal information processing structure regarding starting region of measured ore electrochemical characteristics with a view to develop this ore processing technology at minimal costs, is described.
