    Since no copper is added or removed between the initial and final reaction steps, copper can be quantitatively recovered. In other words, to recover the same amount of copper metal that you started with, this will require careful work. The success of the copper metal recovery will be shown by calculating the percent yield.The Copper Development Association Inc.

    Typical mines today have ore grades of only 0.6 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.The average grade of copper ores in the 21st century is below 0.6 percent copper, with the proportion of ore minerals being less than 2 percent of the total volume of the ore rock.

    Aug 21, 2020 The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic production. Copper was also recovered at mines in three other States.
