After the ore mineralization complex, a product called zinc concentrate is produced, which technical specifications include the grade, type and amount of other minerals associated with it.
Zinc concentrates usually range in the range of 25-30% sulfur and different amounts of other metals such as iron, lead and silver, and sulfur must be separated before zinc metal is extracted by hydroelectrically and pro metallurgical techniques. This work is done through simulation or through zintering.
Classification of zinc concentrate types:

Analysis of the above mentioned products is subject to change due to extraction of minerals from different mines.
