Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in .
Zinc Oxide (ZnO) Zinc Nacional produces zinc oxides by two traditional processes, the "French" process (from refined SHG zinc ingots) and the "American" process (from zinc concentrates and industrial by-products).Both operations are certified under the guidelines of ISO 9001-2008.

In the production of French Process zinc oxide, zinc is melted, then vaporized and drawn into an oxidation chamber. Controlled conditions at the oxidation stage produce the particle size conforming to the individual grades manufactured. When cooled, the zinc oxide is collected, sampled, and analyzed to ensure conformity to grade specifications.
