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.
