I had to answer this for homework, this question didn't help me as there was not any answers but I found something on the cycle of metal...
INGREDIENTS
Metal is a material that is mined from earth. There are many different types of metals. Many of the metals that get thrown in the garbage are scrap metal. Scarp metal is metal we don't want any more like old cars or construction waste. Metal is not biodegradable. But, it can be recycled to make many other useful products.
HISTORY
People have used metals from the beginning of times. They even named whole period of history after metals like Copper Age. Since then people have been using metal for many purpose from construction to packaging and car parts. Metals are still mined today. scientists have also found many ways to improve metals so that they can be stronger and have more uses.
USE
Metal is used everyday life everywhere you can think of for example construction workers use them to build houses and buildings, are also in computers and even in your house that you live in.Metal is and important part of buildings just think about it if your house or any building did not have any metal during a hurricane your house would very unstable and would collapse.That is why metal is such an important part of the world to have.Anywhere you look there are probably at least and inch of metal.
LIFE CYCLE
Many types of metal are recyclable and here are a few steel,tin cans,aluminum cans,empty aerosol cans,and aluminum foil plates.After metal is mined it is smelted and processed into many of the products listed above.But do you know what happens to it after it has been used?Well first you have to wash it and it would do the workers at the recycling place good if you crushed them but most people just rinse it and throw it into a recycling bin.After it has been recycled the process starts from the beginning.

What Metal used in aircraft?
the metal used in building most planes is alumiun as this type of metal as it can expand as the pressure in side the aircraft is greater than the pressure outside the aircraft. it is also the lightest suitable metal although boeing's 787 has been constucted with acompisite material.
What is a jump shear used for?
Cutting light gauge metal. I've seen these in 3 foot and 4 foot widths. Slip the metal under the blade and jump down on the bar. Some have been adapted with an electric motor.
What is Pittsburghh joint in HAVC duct work?
Refer to the SMACNA reference for metal duct construction. The Pittsburg joint is used for most commonly fabricated metal retangular ducts. Most modern sheetmetal fabrication shops use a mechanized piece of equipment to create the Pittsbugh joint on one edge of the sheet metal that is being formed into a retangular duct. The Pittburgh joint is basically a series of bends in the sheetmetal that create a female joint that will accept the male end of the rectangular duct. The female joint includes an extended section of sheet metal that is mechanically or manually hammered over the male edge of the sheet metal once it is positioned within the Pittsburgh joint. It is much easier to understand when viewing a piece of flat piece of sheet metal that is being formed into a section of duct with a mechanized piece of equipment found in most sheet metal shops. I have created a Pittsburgh joint with a manual hand break for specialized duct fittings. I hope the information has been helpful. Ralph Pimentel C.B.O.

What is centrifugal casting?
In the centrifugal casting process, molten metal is poured into a spinning die. The die can be spinning either on a vertical or horizontal axis depending on the configuration of the desired part. Ring and cylinder type shapes are cast vertically; tubular shapes are made with the horizontal centrifugal process. Either process may be used to produce multiple parts from just one casting.Because of the high g-forces applied to the molten metal in the spinning die, less dense material, including impurities, "floats" to the I.D. where it is subsequently removed by machining. Solidification is managed directionally under pressure, from the O.D. to the I.D., avoiding any mid-wall shrinkage, leaving a defect-free structure without cavities or gas pockets.Below in sources section is a link with a great deal of information on various castings
What is inver metal?
An inver alloy has been known as a material having a small coefficient of linear thermal expansion. For example, a Fe64Co36 alloy, a Fe66Co34 alloy and a Fe73Co27 alloy are well known as the inver alloys. By employing the inver alloy as a magnetic pole of the recording head, the projection length of the magnetic pole can be reduce to one-tenth of the projection length of the conventional magnetic pole made of the Fe70Co30 alloy. However, saturation magnetization of the inver alloys are very small, e.g., 1.0 T, and their soft magnetic characteristics are insufficient, so they have not been used for magnetic poles
What happens to ore after it's been mined?
Extracted Ore is crushed smelted, a chemical process usually requiring huge quantities of heat at very high temperature, to extract the metal from the mineral that was the ore. Eventually each specific ore deposit is exhausted and the mine falls into disuse.
What are the metals called which occur in the rocks in the form of?
The metal in rocks is metal ore. Copper ore, iron ore, and so on. In general, once the ore has been quarried or mined, the ore is crushed and smelted (heated to a high temperature) allowing the now molten metal to be retrieved. The waste rock is dumped. Further processing is needed to obtain a finished metal in as pure a state as possible.
What happens to metal after it has been mined?
Just answered a similar question to this, I feel like be nice today and spending 2 secs answering this incase someone else comes along and is kind of bugged that this question didn't have an answer, anyway got to be quick so I can finish my homework and watch the X Factor 2010, I love ONE DIRECTION
When was mining discovered?
Mining dates back to ancient times, with evidence of early mining activities found as far back as 40,000 years ago. The discovery of mining likely occurred when early humans realized they could extract useful materials such as flint, clay, and metals from the earth's surface for tool-making and other purposes.
What happens after the metal has been in contact with the acid for some there?
Ewan ang hirap. .
Is uranium a is uranium a renewable or nonrenewable resource?
Nonrenewable. It is a metal that is mined (dug out of the earth) when it has all been dug up, it's gone. Nothing make more uranium.
Is Antarctica still mined?
Antarctica has never been mined and will not be mined, based on The Antarctic Treaty System, which forbids mining, among other enterprises.
Where is dubnium mined?
The element dubnium is not mined. This metal is what is called a transactinide element, and it is not found anywhere in nature. All of the dubnium on earth has been synthesized in high energy physics laboratories. Additionally, all of it is unstable, and it is, therefore, radioactive. Use the link below to learn more about this element.
What is mined is England?
Although most of England's mineral reserves have now been mined out, in the past coal, oil, clay, stone, tin, copper, lead and iron were mined.
How much gold has been mined?
161,000 tons
Can you build on land after its been strip mined?
If its been properly reclaimed, usually.
What metal was mined in Wales?
There have been, and indeed still are, several metals mined in Wales, the principle one being iron ore. Wales also has copper, tin and even gold mines, many of which still work today operated by private companies. Welsh gold is of great purity and high quality.
