  • Copper Mining and Extraction: Oxide Ores

    Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (1114), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores.

    Every time you switch on a light, use an appliance in your home, or turn on a tap, it is copper that is delivering the electricity or water to you. Copper is therefore a very important metal to humans and combines more useful properties than probably any other metal. An average family home contains more than 90 kilograms of copper: 40 kg of electrical wire, 30 kg of plumbing, 15 kg of builders hardware, 9 kg inside electrical appliances and 5 kg of brass goods. A Boeing 747200 jet plane contains about 1.8 tonnes of copper. The Statue of Liberty in New York contains more than 27 tonnes of copper.

    Copper is the only naturally occurring metal other than gold that has a distinctive colour. Like gold and silver, copper is an excellent conductor of heat and electricity. It is also very malleable and ductile. Copper is also resistant to corrosion (it does not rust very easily). Copper is soft but tough. It is easily mixed with other metals to form alloys such as bronze and brass. Bronze is an alloy of tin and copper and brass is an alloy of zinc and copper. Copper and brass are easily recycled¿perhaps 70% of the copper now in use has been recycled at least once.

    Today copper, because it is such a good conductor of electricity, is used in electrical generators and motors for electrical wiring and in electronic goods, such as radios and TVs. Copper also conducts heat well, so it is used in motor vehicle radiators, airconditioners and home heating systems. As copper does not corrode easily it is also used for water pipes. Its malleability means that copper pipes can be bent to go round corners easily, without breaking. Copper sulphate is used as a fungicide to stop plant roots from blocking drains and sewerage systems. The bluegreen colour of treated timber is the result of copper naphthanate and copperchromearsenate which have been introduced under pressure to help protect the wood from borers. Copper is also used for making coins and scientific instruments as well as in decorative applications. There is about 15 grams of copper in a mobile phone and recently copper has been replacing aluminium in computer chips.

    Copper was the first metal used by people. It was discovered by Neolithic Man about 9000 years ago and used in place of stone, as it was far easier to shape. Early coppersmiths in Iran found that heating copper softened it and hammering copper made it harder. In this way, they could shape copper into various useful items such as containers and utensils¿a big leap forward for the human race. Its beautiful colour also made copper attractive for use in jewellery and ornaments. There is evidence that copper was used from early times, a piece of copper tubing used 5000 years ago was unearthed by archaeologists from the Pyramid of Cheops in Egypt. Around 4000 BC, bronze (an even harder alloy) was discovered by mixing copper with a small amount of tin. It was used to make weapons, armour, tools and decorations tools¿thus began the CopperBronze Age. Although the manufacture of bronze tools largely fell into disuse with the onset of the Iron Age about 1000 BC, copper continued to be used fo

    Because copper reacts readily with other substances, it can be formed in a variety of ways in the Earth's crust. It is often found in deposits with other metals such as lead, zinc, gold and silver. By far the largest amounts of copper are found in the crust in bodies known as porphyry copper deposits. These deposits were once large masses of molten rock that cooled and solidified in the Earth's crust. As they cooled, some large crystals grew, which were then surrounded by smaller crystals as cooling became more rapid geologists call these rocks porphyries. At first, the copper was spread throughout the large mass of molten rock in low concentrations. As the magma cooled and crystals began to form, the amount of melt became smaller. The copper remained in the melt, becoming more and more concentrated. When the rock was almost completely solid, it contracted and cracked and the remaining copperrich fluid was squeezed into the cracks, where it too finally solidified. Over many milli

    In Australia, the search for copper began soon after European settlement. The first major discovery of copper in Australia was at Kapunda in South Australia in 1842 when Francis Dutton found copper ore whilst searching for lost sheep. By the 1860s, South Australia was known as the 'Copper Kingdom'because it had some of the largest copper mines in the world. Australia holds a substantial portion of the worlds copper and was ranked 2nd behind Chile in 2016, according to the United States Geological Survey (USGS). We have several copper mines which are of world significance, including the Mt Isa copperleadzinc deposit in Queensland and the Olympic Dam copperuraniumgold deposit in South Australia which is mining out one of the largest copperbearing deposits in the world. Other examples of important copper resources are at the Prominent Hill and Carrapateena coppergold deposits in South Australia, Northparkes coppergold, CSA copperleadzinc and Girilambone copper deposits in Ne

    Although large copper deposits are mined by opencut methods in many of the major producing countries, most of the copper ore produced in Australia comes from underground mines. The traditional method used at most mines involves the ore being broken and brought to the surface for crushing. The ore is then ground finely before the copperbearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper. The concentrate is then processed in a smelter.

    At some Australian mines, the copper is leached from the ore to produce a copperrich solution which is later treated to recover the copper metal. The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper. The copperrich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex. This is concentrated and the solution is passed to the electrowinning plant to recover the copper. The copper cathodes produced by electrowinning contain 99.99% copper which is suitable for electrical uses. This entire process is known as solvent extraction electrowinning (SXEW). Various methods of smelting are used to convert the concentrates to copper metal. One method is to melt them with fluxes in a smelter furnace to produce copper matte, which is a mixture mainly of iron and copper sulfides usually containing 50 to 70% copper. The molten matte is poured into a converter, which contains more flux
