Copper is reddish in colour and takes on a bright sheen. It is also malleable and ductile, which means it is easily manipulated into another shape. It is usually in the form of wiring.

All American coins are now copper alloys, and gunmetals also contain copper.

Copper is perfectly safe to touch and smell although excess copper is toxic.

Australia is the western world’s fifth largest copper producer.

The largest amounts of copper are found in the earth’s crust as a copper deposit.

The majority of copper comes from seven kinds of ores. Copper ores usually contain less then 4 % copper. Some ores may yield as less as 0.2 % copper. The main copper ores are sulphides, which include bornite, chalcocite and chalcopyrite.

Oxidized ores like azurite, cuprite and malachite, also yield valuable amounts of copper.

Almost pure copper called “native copper” rarely occurs in nature.

The biggest mines in Australia are Olympic Dam and Mt Isa Mines. There is a lot of copper mineral around Au

Copper’s greatest percentage of use is in electrical wiring and motors. Copper is a good conductor of heat and electricity- hence its use in wiring. Brass and bronze are both copper alloys and are extensively used. All American coins are now copper alloys and gun metals also contain copper.

Australia is the fifth largest copper producer in the western world. Some of the other major copper producing areas in NSW are Cobar, Parkes and Orange.

The crushed ore is then conveyed by 1.6 kilometre cable belt to the U62 hoisting system where 36 tonne skips are used to take the ore to the surface for 100% extraction.
