India Was the First to Smelt Zinc by Distillation Process By D.P. Agrawal & Lalit Tiwari. Zinc is a very interesting metal and was responsible for the innovation of utensils of mock silver and coins of mock gold. Because of the low boiling point (907 ° C) zinc is difficult to smelt. Brass (an alloy of copper and zinc) however is known from ...

Smelting Defined. Smelting is the process of extracting a metal from its ore. Hearing this, you might picture simply separating a piece of metal from a huge chunk of rock, but there's more to it. Ore is not just a mixture of rock and metal. The metal found in an ore is often oxidized so you need a chemical transformation to strip the oxygen ...
