Extraction. First you have to grind the ore to a powder. Then you separate the copper minerals from the waste (see the Flotation Process below). Then you need to heat the powder with carbon to burn off impurities. This is called smelting. Less that 1% of copper ore is copper.

Sep 18, 2014Water is a covalent molecule (H20) held together by shared electrons in covalent bonds. During electrolysis, the molecules are reduced at the cathode to to hydrogen gas, and oxidised at the anode to oxygen gas. Pure water doesn't conduct electricity, so we need to add an electrolyte, like bicarbonate of soda.
