The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.

Lead smelters have existed in the world since ancient times when mankind invented metallurgy and started producing the lead from ores. Ore mining and smelting in South Poland started in the twelfth century and intensified in the 19th and 20th century, changing the purpose of smelting from lead to zinc (Popiołek, 1965; Greiner, 2004; …

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.

smelter is a facility engaged in the production of lead metal from lead sulfide ore concentrates through the use of pyrometallurgical techniques (smelting). A secondary lead smelter is a facility at which lead-bearing scrap materials (including but not limited to lead-acid batteries) are recycled by smelting into elemental lead or lead alloys.
