Is Awaruite magnetic?
The alloy has a high specific gravity and is extremely magnetic allowing for physical separation without the use of chemicals.
Where does nickel iron come from?
It occurs in the gold washings of the Gorge River, N.Z.; in the platinum sands of the Bobrovka River, Urals; and in the gold dredgings of the Fraser River, B.C. It also occurs in large ellipsoidal masses (some weighing more than 40 kilograms [about 90 pounds]) in Oregon. Nickel–iron also can be of meteoritic origin.
Where to find josephinite in oregon?
Josephine Creek drainage
Josephinite (Ni3Fe) and Oregonite (FeNi2As2) are both found in the Josephine Creek drainage to the west of Kerby, Oregon. Josephinite is magnetic but not Oregonite making it the rarer of the two, and once commonly found in the placers along the creek.
Is there iron in nickels?
An iron–nickel alloy or nickel–iron alloy, abbreviated FeNi or NiFe, is a group of alloys consisting primarily of the elements nickel (Ni) and iron (Fe)….Alloy summary.
|Name||Description||Chemical formula / Weight percent nickel|

Where is Pentlandite found?
Pentlandite is found within the lower margins of mineralised layered intrusions, the best examples being the Bushveld igneous complex, South Africa, the Voiseys Bay troctolite intrusive complex in Canada, the Duluth gabbro, in North America, and various other localities throughout the world.
What is nickel iron used for?
Nickel-Iron Alloys It is also used at cryogenic temperatures because of its very low thermal expansion rates. Alloys containing 72-83% nickel have the best soft magnetic properties and are used in transformers, inductors, magnetic amplifiers, magnetic shields and memory storage devices.
Where does nickel come from naturally?
Nickel typically occurs naturally in an impure form as ore. It must be mined, extracted and refined. It is mined in a couple of dozen countries around the world, the most prolific of which include Russia, Australia, Indonesia, and Canada.
What is an Oregon Sunstone?
What are Oregon Sunstones? Sunstones are feldspar crystals that formed in lava. Thirteen to fourteen million years ago, a volcano in Steens Mountain erupted, pouring out massive amounts of lava. The lava flow was subsequently covered by a vast lake and remained underwater for thousands of years.
What is Oregon State gemstone?
Sunstone (Oregon State Gemstone) Oregon’s state gemstone is a feldspar crystal that weathers out of certain lava flows in south-central Oregon. Sunstone color relates to the amount of copper in the stone – 20 parts per million for yellow, 200 parts per million for red.
Who was nickel discovered by?

Is pentlandite a mineral or rock?
pentlandite, a nickel and iron sulfide mineral, the chief source of nickel. It is nearly always found with pyrrhotite and similar minerals in silica-poor rocks such as those at Bushveld, S.Af.; Bodø, Nor.; and Sudbury, Ont., Can. It has also been found in meteorites.
