Uses of Zinc | Supply, Demand, Production, Resources
Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
Zinc Sulfide/ Zinc Sulphide (ZnS) - Reade Advanced Materials
Zinc Sulfide occurs naturally as "blend," and is prepared directly from the elements and by precipitation of a zinc salt solution with ammonium sulfide. It is produced at a relatively low cost so many of its applications are as a substitute for other materials. ZnS is a gray or off white powder that is insoluble in water, but soluble in acid.
