Copper is the first metal used by the humans and extended use of its alloy bronze resulted in a new era, Bronze age. Copper is used for making coins and ornaments along with gold and other metals. Copper and its alloys are used for making wires, water pipes and other electrical parts. Question 24.
#0183;#32;Copper, a chemical element that is a reddish, extremely ductile metal and an excellent conductor of electricity and heat. The pure metal is second only to silver in thermal and electric conductivity. Copper is commercially produced mainly by smelting.
You asked what ore gold is found in. The phrasing of the question indicates either a poor command of English or a serious lack of geologic knowledge. I am going to assume your lack the relevant geologic knowledge. The short answer is that: 1 the...
Alloying gold with other metals changes the color of the finished products (see illustration). An alloy of 75% gold, 16% silver and 9% copper yields yellow gold. White gold is an alloy of 75% gold, 4% silver, 4% copper and 17% palladium. Other alloys yield pink, green, peach and even blackcolored metals.

Copper ore is mined for a wide range of industrial applications. Copper, an exceptional electricity conductor, is used as an electrical wire. 4. What type of mineral is gold? Ans: Gold has almost always traced of silver in its natural mineral form, and it can also contain traces of copper and iron. 5. What are the main ores of zinc?
Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth. Illustrations are being added where available.

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.
Copper alloys are some of the most versatile materials. The combination of properties like strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for many applications. The Specifications, Properties, Classifications and Classes are provided for copper alloys.
To know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz
Copper ore. This rock is an ore of copper called chalcopyrite. It is one of the main ores of copper. The metal copper, separated from its ore, is widely used in the electrical industry. Gold Gold has been used and treasured since the ancient civilizations of Ancient Egypt and Mesopotamia.
A few metals, such as gold, silver, and copper can be found in pure form as metal elements. Nuggets or flakes of these metals can be taken straight from rock, but this is uncommon. Metals are used to make many familiar things around us, such as copper in electrical wires, aluminum in soda cans, iron in saucepans, and solid gold in jewelry.
