Zinc smelting Wikipedia

parameters affecting zinc recovery by gravity separation and flotation are Economic viability is premised on the selective mining of the zinc oxide oreThe feed to the oxide zinc flotation circuit requires careful desliming prior to flotation and is then floated with a relatively large amount of sulphidizing agent and a Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure The most common zinc concentrate processed is zinc sulfide which is obtained by concentrating sphalerite using the froth flotation method Secondary recycled zinc material such as zinc oxide is also processed with the zinc
