Copper Mining and Processing: Processing of Copper …

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

GCSE CHEMISTRY

27 · Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide.

Copper

Copper is a ductile, coloured metal that has very high thermal and electrical conductivity. Copper was the first metal to be used by man (probably as early as 7000 BC) and was used as a substitute for stone; its malleability enabled tools to be easily shaped by beating.
