Zinc Extraction; In Brief Review from Past to Present
Zinc (Zn) is an important base metal utilized for a variety of applications in the metallurgical, chemical and textile industries. It is the most produced non-ferrous metal after aluminum (Al) and copper (Cu). In 2020, global world Zn mine production is expected to increase slightly to 13.60 million tons from 12.14 million tons last year.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 Zinc refining
