A shrinking particle—shrinking core model for leaching of a zinc ore ...
2009年9月1日 A mathematical model was developed for leaching of zinc from a zinc ore containing silica. It was shown that considering only the chemical reaction of zinc dissolution is not sufficient for estimating the leaching time of the ore. A thin gelatinous layer was considered to cover the reacting core of the ore in order to correct the model prediction.
