How Zinc Ore Is Mined

Zinc ores are recovered by many mining techniques, ranging from open-pit mining mainly in the case of oxidized ore bodies, which are located closer to Earths surface to the normal underground methods used for the more deeply located sulfide ores. The most common underground method of ore extraction is cut-and-fill stoping, in which tunnels are dug to moderate depths, branching away from the mine
