Separating and extracting zinc from ores, refining it, and preparing it into usable forms. Ordinarily, after being mined, ores must first be separated into a concentrated mineral and a waste rock. This concentrate then is reduced to the metal in a metallurgical works. Finally, the metal may be further refined and alloyed to commercially usable form. Commonly, these three extractive metallurgical operations are conducted at separate locations and are broadly categorized as concentrating, smelting, and refining, respectively.
