Smelting copper ore produces copper (Cu) and residues of whatever else was in there. Melting galena (lead sulfide, PbS) at 1114 °C (2037 °F) produces molten galena, smelting it produces lead (Pb) and some sulfur (S) compound.

Copper Smelting Process

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal …

23.2: Pyrometallurgy

Zinc smelting is the process of converting zinc ores into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. There are two methods of smelting zinc: the pyrometallurgical process and the electrolysis process; both methods are still used ...

From Ore to Finished Product

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper Smelting and its Main Control Parameters The raw material for copper matte smelting is a ne sulde concentrate. In flash smelting, for example, the dried concentrate gets in contact with oxygen-enriched air in the burner at top of the reaction shaft. Fe and S are oxidized from the Cu-Fe-S concentrate to produce a Cu-rich sulde
