Does steel occur naturally?
no, steel is one of many manmade alloys. the closest natural material to steel are nickel-iron meteorites.
Where can iron be found naturally?
Iron is found combined with Oxygen, in the form of Iron Oxide (also known as Rust).
How do you buy Jasper stone?
Jasper is a naturally occurring form of chert, a variety of quartz, which owes it's red or orange coloring to impurities of iron.
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
Does steel occur naturally?
no, steel is one of many manmade alloys. the closest natural material to steel are nickel-iron meteorites.
What mineral doesn't occur naturally but must be separated from its ore and its harder more rust-resistant form of this mineral is steel?
it is iron
Does iron occur naturally or in compounds?
NO!!! It does not occur naturally. However, its mineral ores are very common. e.g. Haematite, Magnetite.
Where can iron be found naturally?

What is the formula of haematite?
Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe2O3.Hematite is Fe2O3.
How do you buy Jasper stone?
Jasper is a naturally occurring form of chert, a variety of quartz, which owes it's red or orange coloring to impurities of iron.
The three substance that form natural magnet are?
Iron, Nickel, and Cobalt
Does iron or oil form faster?
Oil, a complex mixture of hydrocarbons, takes millions of years to form naturally. Iron is a naturally occurring element, formed by fusion in the core of a star. As far as humans need be concerned, iron is always present and oil is formed. If you must have one faster than the other, iron is formed faster than oil.
What useful material can be obtained from hematite?
Hematite is the naturally occuring mineral form of Iron (III) Oxide, or Fe2O3. As such, it is possible to extract pure iron from it.
What mineral doesn't occur on earth naturally but must be separated from its ore?
Iron
Can iron be magnetised?
Iron is naturally magnetized.
How many natural occurring elements are there?
9290, technetium and promethium are radioactive with short halflives, they do not occur naturally.Of the 118 elements that are known, 94 occur naturally. The elements that do not occur on earth naturally, have been produced artificially. Some of the elements that do not occur on earth naturally have been detected in other parts of the universe. See link for more information.Tc and Pm of number 1-92 had not been found naturally until fairly recently, but now they have. Promethium, technetium, neptunium and plutonium are now considered natural chemical elements as trace quantities have been found in nature; consequently, 94 natural chemical elements.We know today there are 118 elements total. So far.94 are considered natural elements as we can add promethium, plutonium and neptunium to natural elements because these elements exist in nature in ultratiny trace quantities.About thirty native elements are known to occur naturally, by themselves, in pure form, uncombined with other elements into minerals. They include metals like copper, gold, lead, and iron; semi-metals like antimony, arsenic, bismuth, and tellurium, and non-metals like diamond, sulfur, and selenium.Some elements decay into other elements very quickly and very little of them remain. However they can be produced in laboratories and during supernova explosions.90, technetium and promethium are radioactive with short halflives, they do not occur naturally.Astatine has an even shorter half life, being furiously radioactive. Make it 89 ?90 elements out of the first 92 elements are naturally occurringThere are 88 naturally-occurring chemical elements90, technetium and promethium are radioactive with short halflives, they do not occur naturally.98
