The zinc vapour is absorbed into the lead, and, by withdrawing the lead continuously and cooling it, the saturation point of zinc in lead is reached and molten zinc separates as a distinct layer on the surface. On removal of the zinc overflow, the partially cooled lead is returned to carry out further shock-chilling.In existing smelters, cylindrical furnaces vary in area from 15 to 27 square metres and capacities range
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

Minerals Extracted. Surface mining is commonly used to extract coal and copper, and increasingly, precious metals like gold. Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart.
Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from low-grade deposits by surface mining.

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
Zinc is the 23 rd most abundant element in the earths crust. 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.
