Zinc and lead are closely bonded with each other and co-exists in raw ore. For example, galena (PbS) and sphalerite (ZnS) are detected as associated minerals in natural mines. Most of zinc metal production are from zinc sulfide ore, which mainly exists in the form of sphalerite, maramatite and wurtzite.

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.
