how to extract copper from copper ores
Extraction
Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

How do you separate copper from copper ore? – Rehabilitationrobotics.net
How is copper extracted from hydrometallurgical process? 1. A ferric sulphate leach step to extract copper from chalcocite (Cu 2S) in the sulphide ore or concentrate. This leach enables use of simple atmospheric reactors, gives good copper extraction, and allows regeneration of the leachate using bacteria or pressure oxidation of the liquor.

Why do we extract copper from low grade ores?
Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process
Copper minerals, even though minor components of precious metal ores, dissolve in these cyanide leaching solutions, consume cyanide, cause fouling of mill solutions, and thus interfere with the precipitation and recovery of gold.2,3,4 Here is a summary of laboratory investigations on the use of cyanide solutions as extractants for copper from various copper-bearing ore fractions.

The Extraction of Copper
The metal copper can be easily extracted BUT copper–rich ores are becoming scarce so new methods of extracting copper are being developed to exploit low grade ores. A low grade ore is one with low concentrations of copper and research is going on to try and exploit waste material left over from processing high grade ores.

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. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide.
