the final mining process of zinc ore

Zinc – Mining and Processing
2022-1-21 · Methods of Zinc Extraction. Depending on what kind of ore is mined and whether it is situated above or beneath the surface, there are different ways of extraction. During the mining process, solid blocks of material (ores) are taken out of the ground for further processing. Open-Pit Mining. Open-pit mining is usually used for oxide ores.
