The low grade zinc of residue leads to high consumption of energy in pyrometallurgical processing such as carbothermic reduction[1] because of heating high contents of gangue materials, and only 70% total Zn recovery can be obtained.
In the first stage, ZPR was roasted, after blending with concentrated H2SO4, The second stage of the current research focuses on the leaching of the residual material from the first stage with water to bring zinc into solution Experimental Materials.

The phase was prepared by heating the starting materials to 192 hours includes many grinding and sieving processes.
ZnO materials (20-nm average grain size) were introduced at the final step after 144 hour of sintering.
In fact, as observed by many authors [7], small amounts of nano-materials can heal microcracks and increase the connectivity between grains.
