achite (Cu2 (OH) 2 co3).Copper ore smelted from Crude copper, finally get the pure copper through electrolytic refining
For industrial applications, oxygen-free Cu cathodes is valued more for its chemical purity than its electrical conductivity. High-pure grade copper plate is used in plasma deposition (sputtering) processes, including the manufacture of semiconductors and superconductor components, as well as in high vacuum devices such as particle accelerators. In any of these applications, t
