The mining process. the mining process. 1. mining open pit and underground. to define the ore from the waste rock, samples are taken and assayed. assay results are used to mark out areas of ore and waste rock, which are mined separately. some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
Within the united states, mining and production of copper are primarily located in the west, specifically arizona, new mexico, utah, nevada and montana. according to the united states geological survey usgs, production in these states and michigan account for more than 99 of domestic copper production. copper is used in many different industries, including building construction, transportation, electronics and consumer goods.
Minerals are concentrated in specific types of geologic formations ore bodies, which are where mining takes place. these ore bodies may already contain naturally-occurring radioactive materials norm. the most frequently-occurring radionuclides and their decay products found in copper ore include
Copper mining and processing methods can expose andor concentrate norm, transforming them into technologically enhanced naturally occurring radioactive materials tenorm.
Ores that contain copper in the u.s. are typically mined in large, open-pits. copper processing facilities are usually located near mining or extraction sites. significant waste volumes are associated with copper production. mine wastes may contain radionuclides due to their natural presence in ores and can be a source of tenorm.
Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. however, in the united states this is not a general practice. learn more about uranium mining.
The winu copper-gold-silver discovery in the paterson province of western australia is real and it could be colossal, rio tinto confirms. the major miner announced the discovery of winu aka the worst kept secret in mining after market close yesterday. the low grade mineralisation starts close to surface and runs very, very deep.
Acids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides. the liquid that leaches through the rocks is collected. this liquid contains the dissolved copper, known as a pregnant leach solution pls. the copper present in this liquid is collected and later processed.
A second method is in-situ leaching. groundwater and certain geochemical conditions must be present in order to utilize this method. during in-situ leaching, rather than physically mining and removing overburden to reach copper deposits, chemicals are introduced into ore bodies using injection wells. the pls is then captured in production wells, collected and later processed.
Once pls is leached, it is sent to a solvent extraction plant to remove the copper. the pls is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid. then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material. another process, called electrowinning, uses electricity to extract copper out of the pls onto thin metal sheets.

Copper is found in natural ore deposits around the world. this page explains copper mining the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
Copper minerals are found throughout the earth8217s crust. they occur in both sedimentary and igneous rocks. the outer 10 km of the crust contains 33 g of copper for every tonne of rock and in some places volcanic activity, millions of years ago, deposited molten copper in one location. it is these areas which are mined today because they contain enough copper to make mining profitable. as well as the valuable copper there is much waste rock called gangue which has to be removed.
The following gives an overview of how copper is extracted from its ore and converted into pure metal.
The ore is removed from the ground in either open pit or underground mines.underground 8211sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore.open-pit 821190 of ore is mined using theopen pitmethod. ores near the surface can be quarried after removal of the surface layers.
An ore is a rock that contains enough metal to make it worthwhile extracting.
Located 560 kilometres north of adelaide, olympic dam is one of the worlds most significant deposits of copper, gold, silver and uranium.
Olympic dam is made up of underground and surface operations and operates a fully integrated processing facility from ore to metal.
The underground mine is made up of more than 450 kilometres of underground roads and tunnels. ore mined underground is hauled by an automated train system to crushing, storage and ore hoisting facilities.
The processing plant consists of two grinding circuits in which high-quality copper concentrate is extracted from sulphide ore through a flotation extraction process. olympic dam has a fully integrated metallurgical complex with a grinding and concentrating circuit, a hydrometallurgical plant incorporating solvent extraction circuits for copper and uranium, a copper smelter, a copper refinery and a recovery circuit for precious metals.

The year 1917 was a watershed for australian copper mining and particularly for copper smelting.
Prior to this time many copper mines were equipped with an on-site smelter, into which high-grade copper ore or a gravity copper concentrate were fed to produce a copper matte with 40 per cent copper for subsequent converting to blister copper 99 per cent copper and refining at centralised copper refineries in australia or overseas. during the early 1900s several on-site smelters were also equipped with converters.
During world war i wwi, copper was in demand and the price was abnormally high. the average annual copper spot price nominal on the london metal exchange peaked in 1917 at 126 and by 1922 had dropped to 63, and reserves of higher grade ore were running out at some mines. the change in copper price is shown in figure1.
This article was inspired by a two-part paper, the evolution of early copper smelting technology in australia, by peter bell and justin mccarthy published in the journal of australasian mining history association in 2010 and 2011. the paper included descriptions and comparisons of reverberatory furnaces and waterjacket blast furnaces, and converters, and identified 156 copper smelters built in australia between 1847 and 1918.
The hampden smelter at kuridala, south of cloncurry, consisting of two waterjacket blast furnaces and a converter section, produced blister copper from 1911 until the drop of the copper price in 1918, and again for a period in 1920. various waterjacket blast furnaces were used at the nearby mount elliott mine site from 1909, but the smelter closed in 1919 following falling copper prices.
The mount cuthbert smelter north-west of cloncurry was commissioned in early 1917 and comprised a single waterjacket blast furnace and two converters, smelting ore from local mines, which was previously transported by rail to the smelter at mount elliott. the mines and smelter closed in 1920.
The corella copper company commissioned a 60td waterjacket blast furnace adjacent to the rosebud mine west of cloncurry in 1915, but falling ore reserves and copper grade prompted the closure of the rosebud and satellite mines, and the smelter, in 1917.
The great cobar operation was one of several copper mines in the cobar district of new south wales and had three waterjacket blast furnaces, and three converters commissioned in 1907. the mine and smelter were closed in 1914, and smelting recommenced in 1916, continuing until 1919. there was a small waterjacket blast furnace commissioned at the cornish, scottish and australian csa mine in the cobar district in 1917 and this was superseded by a larger waterjacket blast furnace in 1918. the csa mine closed in 1920 following an underground fire.
The small state smelting works at phillips river west of esperance on the south coast of western australia was commissioned in 1904. there was a waterjacket blast furnace, and a later concentrating plant and converter added to produce blister copper. the smelter closed in 1918 due to the fall in the price of copper.
The copper smelters and furnace types operating in australia in 1917 and since that time are shown in figure 2.
