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.

Meanwhile, compared to developed countries, such as USA, Germany, Japan and other countries in the world, there are many major gaps in manufacturing of benchmark in precision equipment: Different throttle modes: It adopts mounted orifice technology in China[5], at the same time, it forms orifice directly on the substrate, or it utilizes porous materials overseas.
Materials: In China, the guide rails are mainly made of marble, but mainly aluminum in foreign countries; In China, the flotation devices are mainly made of 38CrMoAl or stainless steel, however, mainly aluminum in foreign countries.
The anti-bending section moments of inertia J is the evaluation, affecting the individual stiffness of guide, thus, according to the formula in mechanics of materials, it may determine the level of stiffness by analyzing the size of J under the same conditions.
