Optimization of Bioleaching Conditions of Pyritum Using
Objective: To optimize bioleaching parameters of pyritum using Acidithiobacillus ferrooxidans (A.f). Method: With leaching rate of pyritum as index
three variables including concentration
pH and temperature of pulp were investigated by response surface methodology. Result: A quadratic polynomial regression model was developed and optimized bioleaching conditions were as follows:pulp concentration 0.97%
pH 1.82
temperature 34.75℃.Bioleaching rate of pyritum was up to 82.04%
it was close to the predicted value. Conclusion: This optimized technology was simple with high bioleaching ratio and good reproducibility.
