Copper Smelting Chemistry Tutorial

A typical copper ore contains between 0.5% and 2.0% copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.

What Is Silver Smelting? (with pictures)

Aug 01, 2020· Zinc concentrates that contain silver are also roasted and sulfuric acid is added to leach away the zinc. Slag fuming is then used to mix the remaining ore with coke and air to produce lead bullion in the silver smelting furnace. This lead bullion is then processed in the same way that lead ores are to produce silver, using the same type of smelting equipment.
