Sphalerite zinc sulfide is and has been the principal ore mineral in the world. Zinc is necessary to modern living and in tonnage produced stands fourth among all metals in world production - being exceeded only by iron aluminum and copper. Zinc uses range from metal products to rubber and medicines. About three-fourths of zinc used is consumed as metal mainly as a coating to protect iron
