What is Zinc Refinery Processes Explained about?

This document provides an overview of the zinc refining process at a zinc refinery. It describes the key steps in the process - roasting, leaching, purification, and electrolysis. In roasting, zinc sulfide concentrate is oxidized to zinc oxide and sulfur dioxide. In leaching, sulfuric acid is used to dissolve the zinc oxide. Impurities like iron are removed through precipitation. The purified solution then undergoes electrolysis where zinc is plated out at the cathode.
