Copper (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans.

The group boasts a diverse and talented board of directors and industry experts with decades of experience between them. The Group undertook a number of divestments and completed a major restructuring in 2014 which have transformed it into a high growth copper company focused on large scale, low cost open pit mining in Kazakhstan. Following completion of the restructuring on 31 October 2014 the Company was renamed KAZ Minerals PLC. Find out more Copper is a specifically valuable mineral.

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral

Bronze, being a manmade alloy of primarily copper and tin, can't be put into any mineral group.
