Jun 17, 2007018332It is somewhat complicated. I recommend reading the Wikipedia article below for more detail. A simplified explanation perhaps overly simplified the concentration of copper in most ore is fairly low and it needs to be concentrated for extraction, oxide ores can be concentrated relatively inexpensively by leaching with sulfuric acid, while sulfide ores are resistant to leaching and a more ...Read More
An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore 0.2. Copper minerals are found in over one hundred varieties, although only a few have been worked for copperRead More
agglomerated ore the ore was rst cured for 14 days and then leached for 90 days. The highest copper extraction, 50.23, was achieved at 32.9 C with the addition of 0.6 kg of H 2SO4 per ton of ore, 0.525 kg of NaCl per ton of ore, and 0.5 kg of FeSO4 per ton of ore. In respect to copper extraction,Read More

Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained oxide is then reduced with carbon or any other suitable reducing agent to obtain the metal.Read More
