A typical copper ore contains between 05 and 20 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

Copper Ores An ore is a rock containing enough valuable mineral to make it worth extracting In the case of copper it is worth extracting when there is about 2 kg of copper per 1000 kg of ore 02 Copper minerals are found in over one hundred varieties although only a few have been worked for copper on a large scale

Copper smelting is typically a twostage process with a feed of copper ore or concentrate to a roaster or sinter plant to agglomerate the concentrate and remove some sulfur This material along with fluxing minerals and a fuel such as coal or oil is then fed to a furnace where a copper matte is produced
