Zinc: Smelting, Producing And Classification-Metalpedia

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. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide.

A process for recovery of zinc values from aqueous ammoniacal solutions employing certain alkylsalicylaldoximes or acetophenoximes as the extractant. The method also provides a means for separation of the zinc and copper values present in the aqueous ammoniacal solution. The zinc and copper values are separately recovered from the organic phase by pH controlled stripping.
