Helium is usually produced as a byproduct of natural gas processing. Natural gas contains methane and other hydrocarbons, which are the principal sources of heat energy when natural gas is burned. Most natural gas deposits also contain smaller quantities of nitrogen, water vapor, carbon dioxide, helium, and other non-combustible materials, which lower the potential heat energy of the gas. In order to produce natural gas with an acceptable level of heat energy, these impurities must be removed. This process is called upgrading.
There are several methods used to upgrade natural gas. When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is often used in order to recover the helium content. Once the helium has been separated from the natural gas, it undergoes further refining to bring it to 99.99+% purity for commercial use.
Here is a typical sequence of operations for extracting and processing helium.
PretreatingBecause this method utilizes an extremely cold cryogenic section as part of the process, all impurities that might solidify-such as water vapor, carbon dioxide, and certain heavy hydrocarbons-must first be removed from the natural gas in a pretreatment process to prevent them from plugging the cryogenic piping.- 1 The natural gas is pressurized to about 800 psi (5.5 MPa or 54 atm). It then flows into a scrubber where it is subjected to a spray of monoethanolamine, which absorbs the carbon dioxide and carries it away.
- 2 The gas stream passes through a molecular sieve, which strips the larger water vapor molecules from the stream while letting the smaller gas molecules pass. The water is back-flushed out of the sieve and removed.
- 3 Any heavy hydrocarbons in the gas stream are collected on the surfaces of a bed of activated carbon as the gas passes through it. Periodically the activated carbon is recharged. The gas stream now contains mostly methane and nitrogen, with small amounts of helium, hydrogen, and neon.

How is helium separated from other matriels that it is found with?
Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.
Where do they get helium for balloons and other uses?
Helium is extracted from natural gas deposits deep underground. It is separated from the other gases in the natural gas through a process called fractional distillation. Once extracted, helium is stored in tanks and can be used for various purposes, including filling balloons and in scientific and industrial applications.
How is aluminum separate from other materials found with it?
Aluminum can be separated from other materials through a process called extraction. This typically involves melting the aluminum-containing material and then utilizing techniques like electrolysis or chemical reactions to separate out the aluminum from other elements present. The lightweight nature of aluminum makes it possible to extract it efficiently from heavier materials it may be combined with.
How do you separate steel?
Steel can be separated using methods such as magnetic separation, which takes advantage of steel's magnetic properties. Another method is through density separation techniques, where the steel can be separated based on its density compared to other materials in a mixture. Furthermore, mechanical processes like shredding and screening can be used to physically separate steel from other materials.
How is neon separated from other materials found with it?
"Neon can be recovered from large nitrogen plants as well as multi-product air separation units. Krypton and Xenon have higher boiling points than oxygen, from which they can be separated by distillation in air separation plants. When these products are recovered from ammonia plant purge gas, the neon must be separated from hydrogen and nitrogen, and the krypton and xenon from methane. " http://www.uigi.com/rare_gases.html http://environmentalchemistry.com/yogi/periodic/Ne.html This should : It can be prepared by liquification of air and separated from other elements by fractional distillation. Annual world production is around 1 ton. help a little at least. Good luck! ~Starburstia~

Why does your body need helium?
Your body does not need helium. Helium is an inert gas, and it is not found as a "building block" of any organic material, or any other materials for that matter.
How is silver separated from the other materials found with it?

How is silicon separated from other materials found with it?
Silicon is typically separated from other materials by several methods including chemical processes such as acid leaching, precipitation, and electrolysis. These methods utilize the differences in chemical properties and solubility of silicon compared to other materials found with it, allowing for the effective separation of silicon.
How is argon separated from other materials its found with?
Argon (and the other noble gases) is separated by fractional distillation of liquid air.
What other material is found in helium?
helium is chemically inert and is not found in any materials
How is radium separated from other materials found with it?
Radium is typically separated from other materials found with it using chemical processes, such as solvent extraction or ion exchange chromatography. These methods exploit the chemical properties of radium to selectively separate it from other elements. Once separated, radium can be further purified through methods such as precipitation or distillation.
How is rutherfordium separated from other materials found with it?
For the first time the products of the nuclear reaction were transformed in chlorides and the rutherfordium tetrachloride was separated by gradient thermochromatography.
How is neon separated from other materials found in it?
Neon is separated from other materials found in it through a process called fractional distillation. This method takes advantage of the differences in boiling points of the various components in the mixture to separate them. In the case of neon, it has a lower boiling point than other components, allowing it to be easily separated and collected.
How does radon become separated from other materials found with it?
Radon is a gas that naturally emanates from the decay of uranium found in rocks and soil. It can be separated from other materials through ventilation systems that allow the gas to escape into the atmosphere. Radon testing and mitigation techniques can also be used to reduce its concentration indoors.
