2022-1-21 · 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

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical

2013-11-8 · 6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
