Zinc smelting - Wikipedia

The remaining calcine is then leached in strong sulfuric acid to leach the rest of the zinc out of the zinc oxide and zinc ferrite. The result of this process is a solid and a liquid; the liquid contains the zinc and is often called leach product; the solid is called leach residue and contains precious metals (usually lead and silver) which are sold as a by-product. There is also iron in the ...

Ultrafine grinding is one method for liberating of locked gold for some ores if efficient size reduction is obtained [6]. Ultrafine grinding followed by cyanide leaching can sometimes produce acceptable recoveries.
