History, Deposits, and Production of Zinc

2020-3-30 · The most important mineral for zinc production is the so-called 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.
