Abstract:   (335 Views)
Hydrodynamic factors have been proved to effectively influence the high-performance heap leaching, hence this study evaluates them on column bioleaching of low grade uranium ore. Response surface methodology (RSM) was applied to predict the behavior of effective parameters particle size, irrigation rate, aeration rate and their interactions in the bioleaching process. Obtained results showed that the best model for the recovery of each metal was the quadratic model. The maximum values of uranium recovery at the optimum condition, (d80 5, mm particle size, 0.34, l/m2/min irrigation rate, and 210, l/m3/min aeration rate), were 63.85%. The results from the model and the experimental data show good agreement.
