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.

Uses of Zinc | Supply, Demand, Production, Resources

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
