Extraction Of Copper | Mining, Concentration, Smelting | …
Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides.The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

What is a redox reaction? - A Plus Topper
What is a redox reaction? Many processes that occur around us are redox reactions. These include coustion, rusting, photosynthesis, respiration and decomposition. Redox reactions are chemical reactions involving oxidation and reduction occurring simultaneously. Therefore, redox reaction is also known as oxidation-reduction reaction. It is interesting to note that oxidation is always

Chemical Reaction of aluminum foil in CuCl2 solution - …
I agree with my colleagues to the extent that it is most probably copper metal. However, given that we are starting with an acidic copper chloride solution, and likely there is some oxygen exposure either from the starting water or from air contact, a little more chemistry may be taking place, more precisely, electrochemical (or displaying a surface anode/hode mechanism).
