Is energy saved if we recycle metals?
Yes, you save all the energy that would have been needed to mine fresh ore from the ground and to extract the metal from that ore. The amount of energy needed to collect and sort the recycled metals is insignificant compared to this (especially for metals like aluminum that are very hard to extract from their ores).You only need to use the energy needed to melt the pure metal, which you would have needed anyway after extraction of new metal from fresh ore.
What metal is a lightning rod made of?
Any metal that will conduct electricity. Steel works fine, since it is strong. A ground rod driven into the ground and connected to the lightning rod with a wire or cable. The ground rod is usually copper clad (or plated) steel.
What are the two processes in the extraction of aluminium that require large amounts of energy?
You need a lot energy to melt the metal compound and then you'd need a great deal of electrical energy to extract the metal from the molten compound.
Which metal out of copper and iron is the easiest to extract from it's ore?
yes, it is quite easy to remove cu from its ore because cu is less reactive so less energy is required i.e.it can be removed from its ore by just heating its ore in air for two to three times.
What reactions extract the copper metal from the ore?
There are two main types of reactions used for extracting copper form its ore. In one reaction, copper oxides reduced by carbon to produce carbon dioxide and pure copper. In the second reaction, Copper ore is dissolved, then reduced by iron ions to form Cu+ which forces the copper to let go of its impurities and these copper ions are then fully reduced by a chemical reaction to form Copper metal. See related links for more information about the second reaction.
What are the economic problems with extracting copper?
It does take a lot of energy to extract copper ores from the ground. Sometimes these efforts can be in vein as as little as 0.4% of copper can be found and 96.6% is just waste material. Also, locating copper in the ground can be costly. Then there is the process of digging it up and transporting the ore to places where it can be purified, which is a process which will also cost a lot. Finally transporting the copper from the extraction site to the purification site and then to it's final destination will be expensive. However it is important to mention that copper is NOT the most expensive metal to obtain, due to it not being very radioactive.

How is metal produced from ore?
The ore must be mined, or must be removed from the ground. Then the ore must be processed to extract the metal
Where was brass the metal found?
Brass is an alloy (combination) of copper and zinc so is a manufactured metal NOT a base metal that can be mined from the ground.
Is copper a metal non-metal or metalloid?
copper is a metal
Copper is a non-metal or metal?
Copper is a metal. It is also considered as a mineral as well. You can find traces of copper in your blood.
Is aluminum a renewable fuel?
No, aluminum is a metal. It needs large amounts of energy to extract it from its ores.
What metal is a good conductor of thermal energy and electric current?
aluminum, copper,
How does metal and its ore relate to corrosion?
An ore has tremendous energy put in it to extract it and convert it to metal. Nature abhors energy and always tries to minimize energy. The metal will thus always have the tendency to corrode to get back to the way it is found in nature -its ore.

Is copper an non metal?
No, copper is a metal.
