Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water to which surface active agents have been addedCopper is traditionally known as the red metal after its natural color However it is also known as a green metal for the green patina that it acquires due to weathering Indeed patinized copper is the architectural focal point of many modern buildings for its natural look
