Mar 30, · The Extraction of Zinc from Ores. The most important mineral for zinc production is the socalled zinc blende (ZnS). This means that apart from zinc, the concentrate contains about 20 % sulfur. Additionally, zinc concentrates always contain iron, lead, and silver in varying proportions, because these elements often occur together in the ores.
