Magnetite is a mineral and one of the three common naturally-occurring oxides of iron. Its chemical formula is Fe3O4, and it is a member of the spinel group. Magnetite is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism.
Small grains of magnetite occur in almost all igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak.
The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide.
Lodestones were used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields. The relationships between magnetite and other iron-rich oxide minerals such as ilmenite, hematite, and ulvospinel have been much studied; the reactions between these minerals and oxygen influence how and when magnetite preserves a record of the Earth's magnetic field.
Want to understand more about the difference between Haematite and Magnitite. We currently have a 2Mtpa DSO operation and 8Mtps concentrate operation to commence September 2012 and a mine life in excess of 30 years. Review our career opportunities at http://www.kararamining.com.au
This is a detailed video of us running a smelter to make steel from magnetite. While some of the preliminary processes are absent from this film, I hope there is enough of the actual smelt to give you a good idea of the methods involved. As curators of the art of smelting, we feel it is our duty to keep the knowledge alive and spread it to the ends of the Earth. Human beings have been losing the ability to create, due to automation and large industry. Carrying on this tradition of the current age is important not only for the ability to smelt, but to use and offer the materials required to make historical and traditional tools and blades.

This method is very simple PERIOD
Visit http://www.magnetite.com.au/ for more about Magnetite - the solution to comfortable living! Magnetite improves the level of comfort in your home or office without the hassle of replacing your existing window. It can reduce noise by up to 70% through your existing windows and improve energy efficiency to save on power bills. How Magnetite Works Magnetite creates an air cavity -- the essence of double glazing. Generally, a larger air cavity means better noise reduction. Magnetic panels provide an air tight seal, just like a fridge door. Magnetite also provides a thermal barrier with energy efficient frames and glazing panels. Using optical grade acrylic, the glazing is up to 6 times more thermally efficient than glass and up to 18 times stronger. Window types We have several model...

Email jacobpsweeney@gmail.com with any questions Orgone Energy Water Charger. This was an early version of the water chargers. Geoff explains how to make one. We can send a pre assembled charger sealed with Resin so none of the ingredients escape during shipping and you can charge your own water. In the very near future we will release very exciting charged water to the public at a very low cost that is charged with a new incredible charger. It will benefit humans and some animals a great deal which will be explained in upcoming video's Magnetite from Wikipedia page: Properties Magnetite is the most magnetic of all the naturally occurring minerals on Earth.[4] Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient man ...
You smacked her right between her blue eyes
You didn't think ahead yeah that's what he said
Then everyone of us just turned our backs to him and said
That was not a nice thing to do
I can't believe he was so cruel
But you love your brothers no matter what they say
Yeah you love your brothers no matter what kind of games you play
And it's gonna rain - that's what they say
But we're just gonna cover our heads
And we ain't coming out until we're dead
Oh no
And It's gonna drown all of our sins
But we don't wanna loose what we got
No we don't wanna loose what we own oh no
This stinking alley's full of old cats and dogs
They got no money and they got no home
Once I was one of them but now I'm on my own
It feels so good to be an outlaw
In your perfect world
'Cause you love your brothers no matter what they say
Yeah you love your brothers no matter what kind of games you play
And it's gonna rain - that's what they say
But we're just gonna cover our heads
And we ain't coming out until we're dead
Oh no
And it's gonna drown all of our sins
But we don't want to loose what we got
No we don't want to loose what we own oh no
And it's gonna rain and thats for sure
Yeah it's gonna rain and that's for shure
It's gonna rain and that's for sure
