· The Extraction of Zinc from Ores. 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.
The Processing is Novel and the Operating Cost is Lower: The regrinding process of lead-zinc mixed concentrate eliminates the need to finely grind all the raw ore, which saves the cost of grinding. At the same time, the re-grinding of the concentrate makes the lead-zinc concentrate to improve the monomer dissociation, and it has a good de-drug effect, which creates favorable conditions for the ...
