| Abstract | By means of mathematical design of experiments method, ore pulp electrochemical processing with subsequent copper recovery into flotation concentrates has been studied. Partial dependences and a generalized multifactor equation of copper recovery degree into concentrates have been obtained, permitting to determine optimal conditions of electrochemical processing. A nomogram has been calculated for copper recovery from electrochemically treated copper-containing product with definition of combination of factors providing for copper recovery at the level of 95.0–99.0 %. |
