Carbonate-hosted lead-zinc ore deposits - Wikipedia

Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size.

Photos of Natural Zinc Ore, zinc minerals and specimens

For many years, the chief zinc ore producing country was the United States. The percentage of zinc in the ore mined is frequently very low, and often averages 3 per cent., but this is increased by concentration. The Broken Hill district in New South Wales produces about 20 per cent, of the world's production in the form of concentrates, averaging from 40 to 45 per cent, metallic zinc. Zinc ...
