Refining of zinc and its cadmium content can be accomplished by treating the zinc concentrates and/or zinc-bearing secondary materials using either a hydrometallurgical or pyrometallurgical process. In both processes the concentrate is converted from zinc sulfide to zinc oxide by roasting and at the same time most of the sulfur is removed as sulfur dioxide SO2 .

Zinc refining - Wikipedia
Zinc refining is the process of purifying zinc to special high grade SHG zinc which is at least 99.995% pure. This process is not usually required when smelting of zinc is done through electrolysis processes but is needed when zinc is produced by pyrometallurgical processes because it is only 98.5% pure.. There are various refining methods but the refluxing process is the most commonly used.
