About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.
Ultrascreen ® Generation3 is the disk filter for wastewater tertiary treatment with no equal: for both the choice of the materials and its technology . A machine that revolutionizes the tertiary …
The carbothermal reduction process is a commonly used technology for recovering Zn and Pb from solid waste, in which Zn and Pb-bearing minerals are reduced to metals and volatilized during roasting, then Zn and Pb are oxidized and concentrated in the dust(Lin et al., 2017; Wang et al., 2017a, b; Zhang et al., 2014).

In the alloy materials, their mechanical properties mightly rely on the compositions and concentrations of chemical elements. Therefore, looking for the optimum elemental concentration and composition is still a critical issue to design high-performance alloy materials. Traditional alloy designing method via "trial and error" or domain experts' experiences is barely …
