Copper mining. From ore to copper.Copper can be extracted from its ore by: 1. Traditional mining. underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. 2. Leaching.
Methods of Extraction – Study Material for IIT JEE ...The method employed for extracting a metal from its ores depends on the nature of the metal and that of the ore and may be related to the position of the metal in the electrochemical series. In general, metals with E o < – volt yield compounds which are very difficult to reduce and electricity is usually used for the isolation of such metals.
