In Thomas Edison invented the first electric light, relying on copper to carry the current to it. Within a few years, the mass use of these two inventions caused an incredible increase in the mining and production of copper. 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 copper-rich fluid was squeezed into the cracks, where it too finally solidified. Over many millions of years the rocks covering these deposits eroded away and the deposits eventually appeared at the surface.
A mixture of copper, iron and sulfur is called chalcopyrite CuFeS 2 or 'fool's gold', and tricked many an old-time prospector! Chalcopyrite in Australia is found in rocks that are more than million years old. The sulfides, which yield most of the copper produced throughout the world, generally occupy the deeper parts of lodes which have not been exposed to weathering. Near the surface they are altered by oxidation and other chemical actions to produce oxides and carbonates.
These secondary copper minerals may form rich ore in the upper parts of many deposits, and owing to their characteristic green or blue colour, even small amounts are easily seen in the rocks in which they occur. Copper bearing minerals are commonly found in association with minerals which may contain gold, lead, zinc and silver. 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 when Francis Dutton found copper ore whilst searching for lost sheep.
By the s, South Australia was known as the 'Copper Kingdom' because it had some of the largest copper mines in the world. We have several copper mines which are of world significance, including the Mt Isa copper-lead-zinc deposit in Queensland and the Olympic Dam copper-uranium-gold deposit in South Australia which is mining out one of the largest copper-bearing deposits in the world.
Other examples of important copper resources are at the Prominent Hill and Carrapateena copper-gold deposits in South Australia, Northparkes copper-gold, CSA copper-lead-zinc and Girilambone copper deposits in New South Wales, the Ernest Henry, Osborne and Mammoth copper deposits and copper-gold deposits at Selwyn in Queensland and copper-zinc deposits at Golden Grove and the Nifty copper deposit in Western Australia.
Further resource and production information. Although large copper deposits are mined by open-cut 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 copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. The concentrate is then processed in a smelter. At some Australian mines, the copper is leached from the ore to produce a copper-rich 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 copper-rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex.
