History Deposits and Production of Zinc

30.03.2020  Near the mines in which zinc ore is extracted in underground or open cast operations some plants enrich the zinc content of the ore 5 to 15 to about 55 in so called concentrates The separated rock with low zinc content remains in place In this way less material has to be transported which means that less energy is used for transport and zinc extraction is more environmentally friendly.
