Aims: In this study, copper extraction was investigated from chalcopyrite concentrate
with hydrogen peroxide and acetic acid mix solution by using response surface methodology.
Method: Experiments were planned using Box-Behnken in which various parameters such as
leaching time, leaching temperature, H2O2 concentration, liquid-solid ratio, and stirring speed
were defined as independent variables.
Result: Under optimum experimental conditions, more than 80% of the copper was extracted
with R2 value of 0.94 which indicates good fitness of the model.
Conclusion: Moreover, other parameters except stirring speed were determined to be linearly
effective on the result.
