Zinc - Wikipedia

The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral The largest workable lodes are in Australia, Asia, and the United States Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning )The History of Zinc - RHEINZINK,Introduction Zinc was found to be especially suitable for alloys with other metals and was therefore first of all employed to make coins Although zinc ores have been in use since the Bronze Age, it was not until very much later that zinc was discovered to be an element, ie aZinc chemicals - EverZinc,EverZinc is a global leader in the production of zinc chemicals with four product lines: fine zinc powders, zinc oxide, zinc powders for batteries and Zano®, an ultrafine zinc oxide
