the final mining process of zinc ore

Copper processing

For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 …

Zinc Mining

The techniques used in zinc mining depend on the type and depth of the mineral deposit. Open-pit mining is used for shallow deposits, while underground mining is typically employed for deeper ore bodies. Extraction methods include crushing, milling, froth flotation, and finally, smelting and refining to produce pure zinc metal.
