Jan 20, 2022 Compared to other mined materials, the history of zinc mining is rather short. It started in the 18 th century when it was discovered that zinc can be used to galvanize metals to keep them from rusting. zinc has become a crucial material for metal processing. As zinc is so important for casting plants, metal treatment and metal engineering, the mining process has
