Chemical formula copper ore?
The chemical formula for copper ore can vary depending on the type of ore. For example, chalcopyrite, which is a common copper ore, has a chemical formula of CuFeS2. Other copper ores may have different chemical compositions.
What is the difference between Copper- rich ores and Low - grade ores?
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper

What are four minerals that are commonly taken from ores?
Iron is commonly extracted from hematite and magnetite ores. Copper is often obtained from chalcopyrite and bornite ores. Aluminum is typically derived from bauxite ore. Zinc is commonly extracted from sphalerite ore.
Is extracting metals from ores cost effective?
Minerals are solid elements or compounds found naturally in the Earth's crust. Those minerals that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis. Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2 The resulting copper, however, is pure enough to be used for many industrial applications, but it has to be further refined for electrical uses. That copper is cast into thick sheets known as anodes and are placed in large electrolytic cells filled with a copper sulfate solution. A DC electric current is passed through the cells causing the copper anodes to dissolve and deposits pure copper on the opposite pole called the cathode. The final product is between 99.94 and 99.96% Cu.

The chemical formula for copper ore can vary depending on the type of ore. For example, chalcopyrite, which is a common copper ore, has a chemical formula of CuFeS2. Other copper ores may have different chemical compositions.
What are ores of copper?
the ores of copper are chalcopyrite .malachite .azurite. and native copper.
Do we get copper from trees?
No, copper is a metal. It is obtained by mining various copper ores from underground, then smelting the ore in a very hot furnace to separate the copper from everything else in the ore.
What is the ores of copper?
Ores of copper(Cu) are: -Chalcopyrite -Malachite -Azurite Native copper can also be found.
What is the chemical formula of copper matte?
The chemical formula of copper matte is typically not fixed and can vary depending on the specific composition of the mixture. In general, copper matte is a combination of copper sulfides and other metal sulfides that result from the smelting of copper ores.
What is the difference between Copper- rich ores and Low - grade ores?
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper
What minerals are obtained from gold and copper?
Gold and Copper are chemical elements. No "minerals" can be extracted from them other than 'gold' and 'copper'. They can be extracted from the minerals or 'ores' named in the other answers herein.
How is bismuth mined?
Bismuth is primarily extracted as a by-product of lead, copper, tin, and tungsten mining. When these ores are processed, bismuth is often found in small quantities and can be separated through various chemical processes. Bismuth can also be mined directly from bismuth ores such as bismuthinite and bismite.

Can you mine bronze or do you have to mine the separate components?
Bronze is an alloy of (usually) copper and tin. We mine the metal ores separately and then combine them to make bronze.
Which raw material used in copper?
The ores of Copper are usually copper carbonates such as Malachite.
How is copper normally found in the ground?
In ores. Copper ores are found in various parts of the world. Copper can be found as a metal in the ground. Normally, it is green on the outside. Most copper is not as a metal but in chemical compounds. Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things. Some mollusks and arthropods have blue blood because they have copper in their blood. Animals such as humans and other mammals have red blood because it contains iron. Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper sulfate - sometimes spelt sulphate. Pure copper forms on the negative electrode.
