The extraction of copper from ore is normally carried out in three major steps The first step In the ore dressing plant the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials or gangue In cases where the next step is leaching most frequently in the case of oxide ores
