The present study was conducted during 2004 to develop mathematical models for individual parameter to enrich copper in concentrate from raw copper ore of North Waziristan (Pakistan). The study is based on the primary experimental data with seven important process parameters i.e. type and dosage of collector (X1g/ton), pH (X2), depressant Sodium Cyanide (X3 g/ton), Sulfidizer sodium sulphide (X4g/ton), frothier dosage (X5g/ton), pulp density (X6 % vol/wt) and conditioning time (X7 minute) and consists of 31 observations. Flotation process parameters were studied to concentrate the copper content i.e. chalcopyrite of North Waziristan copper ore. Mathematical models were developed by applying statistical and computational "Excel" Techniques. Forty mathematical models for the recovery of copper have been constructed.
