IV. Methods Of Obtaining Copper From Its Ores

There are three general methods of extracting copper from its ores. The dry, wet, and electrolytic methods. The wet method is used the least of the three, and consists in placing the ores in an acid solution which dissolves the copper, which is then precipitated to the bottom of the tank by the addition of suitable precipitants.

2017-3-27  Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
