摘要

Abstract

This work presents a study for chemical leaching of sphalerite concentrate under various constant Fe

concentrations and redox potential conditions. The effects of Fe

concentration and redox potential on chemical leaching of sphalerite were investigated. The shrinking core model was applied to analyze the experimental results. It was found that both the Fe

concentration and the redox potential controlled the chemical leaching rate of sphalerite. A new kinetic model was developed

in which the chemical leaching rate of sphalerite was proportional to Fe

concentration and Fe

/Fe

ratio. All the model parameters were evaluated from the experimental data. The model predictions fit well with the experimental observed values.
