Copper ore is extracted using two basic methods of mining open pit or underground mining 3 Processing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller piec This is accomplished by a variety of subsequent processing steps 4 Beneficiation of Copper OreGold extraction refers to the processes required to extract gold from its orThis may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of

Extracting copper from other or Copper can be extracted from non sulphide ores by a different process involving three separate stages Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulphuric acid to produce a very dilute copper II sulphate solutionFor example high grade copper ores which contain a high percentage of copper are becoming harder to find and mine It is a slow process the use of scrap iron is a cost effective way to

Metallic ores occur in every kind of rock and some varieties of soil The metallic minerals are concentrated into rich masses by igneous hydrothermal or erosional/weathering process Metals such as chromium platinum nickel copper and iron can precipitate as sulfide minerals in In concentrating copper ores for example pine oil is often used The pine oil binds to the copper compounds but not to the unwanted rocky material The treated ore is then put in a large bath of water containing a foaming agent a soap or detergent of some kind and air is blown through the mixture to make a lot of bubbl
