The optin1un1 leaching conditions or prin1ary chalcopyrite ore tl·on1 Artvin-Murgul region in Turkey have been exan1ined in hypochlorite solution. 'The effects of various paran1eters as initial pH, hypochlorite concentration, stirring speed, solid/liquid ratio and ternperature to the copper dissolution fron1 chalcopyrite were investigated. lt was found thatchc:1lcopyritc reacted \\'ith chlorine generated fron1 hypochlorite in acidic pH values. pi I cfTcctivcly decreased during the di. solution. It was detern1incd that the optin1un1 leaching conditions \vere initial pll of 5-6~ hypochlorite concentration of0.2 N for 4 g/L solid/liquid ratio. 600 rpn1 stirring speed and it was seen that sulphate forn1ation was over 50%.
