Where Is Copper Found Copper can be found underground in the form of copper ore The main copper ore producing countries are Chile the United States Indonesia Australia Peru Russia Canada China Poland Kazakhstan Zambia Zaire and Mexico What Has Copper Been Used for in the Past Copper was one of the first metals used by humans Nov 25 2019 The worlds 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year about 40 of the worlds total copper mine capacity Chile and Peru alone account for more than half of the copper mines on this list The US makes the cut as well with two mines among the top 20 Copper is expensive to mine and refine Typical mines today have ore grades of only 06 percent copper Since metal concentrations occur at much lower grades the copper concentrations are measured in parts per million ppm If a sample has 1ppm copper this means that in 1 million lbs of rock there is 1 lb of copper 4 If a copper concentration comes back from the lab as 100ppm

Copper mining From ore to copper Mining Copper can be extracted from its ore by 1 Traditional mining underground sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore open pit 90 of ore is mined by this method Percentage Of Copper In Ore Can Mine Whats in an ore There are many types of copper ore found throughout the world Picture 4 shows the distribution of these deposits About 80 of all copper extracted comes from sulphide ores A typical ore contains only 05 to 20 copper BotEC Percentage of Copper in Ore Carleton College 30052021 The copper ore forms only 07 of the rock We need to find a number that we can multiply by 007 to get 90 kg Dividing 90 kg by 007 will give us that numberapproximately 12860 kg Multiplying that number by 22 poundskg would give us the number of pounds about 28300

Copper is generally mined and extracted in form of compound ore known as copper oxide ore and copper sulfides ore The copper percentage in particular copper ores generally ranges to 18 from 1 are called copper grade Decreasing Ore Grades in Global Metallic Mining A At present the global average copper ore grades for copper mines is Copper is usually found in nature in association with sulfur Pure copper metal is generally produced from a multistage process beginning with the mining and concentrating of lowgrade ores containing copper sulfide minerals and followed by smelting and electrolytic refining to produce a pure copper Mining 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

Even though the operational costs of biomining are a little higher than the cost of traditional mining more copper can be extracted using biomining as the process can be used for more varieties of rock On average about 60 to 65 percent of the copper from a mine can be extracted using conventional methods whereas 90 to 95 percent can be 100 percent Founded 1903 Kennecott Utah Copper Utah Copper Kennecott Utah Copper is a mining in the huge ore body of the Bingham Canyon Mineget price Visitors can also enjoy a 19minute film detailing the mines history and the process used to produce copper Mar 24 2017 Assume a 5foot section of EX diameter hole 48 inches of core a core assay of 30 percent copper and a sludge assay of 36 percent copper The core assay would receive a weight of 284 and that of the sludge 716 The calculation then becomes Average assay 1100 284 x 300 716 x 36 343 percent copper

According to Cox and Singer the average copper ore grade in the mine x m was 167 around 1990 and in the case of the 25 copper mines analyzed the average ore grade is 148 These selected mines produced more than 5 million tons in 2009 which corresponded to 32 of the total world production that same year 42 The average percentage copper content of the entire ore deposit will be less than the average of the ore accessed in the early years of mining Mining companies will exploit this characteristic of ore deposits to maximize their output in a mines early years in order to pay off debt finance percentage of copper in ore can mine kzsppl Modern copper ores contain less than 06 copper and less than 2 total volume of economic ore minerals including copper Source Ore grade refers to the proportion of gold contained in the ore of a particular mine and is represented in

The ore is then ground finely before the copperbearing sulphide minerals are concentrated by a flotation process that separates the grains of ore mineral from the gangue waste material Depending on the type of copper bearing minerals in the ore and the treatment processes used the concentrate can contain between 25 and 57 copper The duction of cathode copper Assuming an ore grade of 055 percent and a recovery rate of875 64 percent copper in the concentrate concentrating 1 ton of copper ore requires over 200 billion Btu or approximately 42 million Btuton of cathode copper10 Grinding accountsfor roughly 6 0 percent of the total energy consumed in proc Percentage Of Copper In Ore Can Mine In most cases copper ores contain between 06 and 1 per cent of copper Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper In the case of platinum the yield is much lower 1 tonne of ore usually contains between 3

These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine These produce many millions of tonnes of copper ore per year The main ores of copper are sulfides and oxides From their chemical formulas you can calculate the percentage of copper in each mineral Aug 04 2021 Question Suppose that you are building a new house It will take about 90 kg 198 pounds of copper to do the electrical wiring In order to get the copper in the first place someone needs to mine solid rock that contains copper extract the copper minerals throw away the waste rock and smelt the copper minerals to produce copper metal The process used to treat sulfide copper ores begins at the mine site where the copperbearing minerals are physically separated from the rest of the rock The flow diagram below shows how the percentage of copper increases as the ore is refined first physically by froth flotation then chemically by smelting and finally electrolytic refining
