Zinc - Essential Chemical Industry

One process developed in Canada, and capable of recovering 99% of the zinc in the ore, uses pressures in excess of 10 atmospheres and a temperature of ca 420 K. The presence of iron in the ore concentrate is important in this method, as it is in part responsible for the conversion of zinc sulfide to zinc sulfate.
