Copper is extracted in large amounts from the Earth’s crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

3. Extraction (“Mining it”) In the extraction stage the mineral is removed from the earth in large quantities as the mine begins producing. This stage is typically what we envision when we think of mining. Some exploration and development may continue at this stage, as well.

The steps depend on the type of ore, the reactivity of the metal, and the nature of impurities present in the ore. These processes involved in the extraction and refining of the metal are called metallurgy. The ores of most of the metals should be brought to the Earth’s surface for extracting metal from them. This process is called mining.

Either through strip-mining or blasting, raw ore is obtained for extraction of copper. Heap Irrigation The ores obtained from mining are crushed and piled up to 10 meters high atop plastic irrigation pads, whereupon water seeded with acid, called the lixiviant, is irrigated through the heaps and collected (Fig. 2).

Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

The pulp discharged from the grinding mill is transported to the agitation tank, where the flotation reagent is added in rouging flotation stage. After full agitation and activation of the agitation tank, the pulp is fed to the flotation machine.

Since mine tailings have already been part-processed (by comminution, to produce fine-grain particles) the cost of extracting residual metals from them is often economically more attractive than mining a deep-buried primary ore body. In addition, mine wastes may contain metals (such as rare earth elements) that were not considered worth

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Copper is one of the most commonly-used metals worldwide, and many of the largest mining companies are involved in its extraction from the earth. The reddish-gold metal has a range of industrial uses, and is often used in electronics due to its high electrical conductivity and its ability to be easily shaped into wiring.

Copper ore with a content of 0.3 per cent is probably not worth extracting if it lies at a depth of 1000 m, but can be interesting if it is at the surface. This is because extraction costs are lower in an open pit (at the surface) than in an underground mine.
