Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal. Its name is derived from the Spanish term platina, which is literally translated into "little silver".
Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it became investigated by scientists.

Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
Gold's atomic number of 79 makes it one of the higher atomic number elements that occur naturally in the universe. It is thought to have been produced in supernova nucleosynthesis from the collision of two neutron stars and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was just formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is present today in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the late heavy bombardment, about 4 billion years ago.
Miranda Leigh Lambert (born November 10, 1983) is an American country music singer and songwriter who gained fame as a finalist on the 2003 season of Nashville Star, where she finished in third place and later signed to Epic Records. Lambert made her debut with the release of "Me and Charlie Talking", the first single from her 2005 debut album Kerosene. This album, which was certified Platinum in the United States, also produced the singles "Bring Me Down", "Kerosene", and "New Strings". All four singles were top 40 hits on Billboard Hot Country Songs.
After Epic's Nashville division closed, Lambert was transferred to Columbia Records Nashville for her second album, Crazy Ex-Girlfriend, which was released in early 2007. Although the title track failed to make top 40, the next three singles ("Famous in a Small Town", "Gunpowder & Lead", and "More Like Her") were top 20 hits, with "Gunpowder & Lead" becoming her first top 10 country hit in July 2008. Her third album, Revolution, was released in September 2009. Five singles were released from the album, including two Number One hits: "The House That Built Me", which spent four weeks at the top; and "Heart Like Mine". Lambert has also been honored by the Grammy Awards, the Academy of Country Music Awards, and the Country Music Association Awards.

6 quick facts you might not of known about Platinum. 1,Platinum is the rarest and heaviest of the precious metals. All of the Platinum ever mined would fit in the average size living room. 2,Annually, only about 133 tons of Platinum are mined, compared to about 1,782 tons of Gold. 3,More than 90% of all Platinum supplies come from South Africa and Russia. Virtually all of the platinum mined in South Africa is committed to industrial contracts. 4,When World War II began, the U.S. government declared Platinum a strategic metal and its use in non-military applications, including jewelry, was disallowed. 5,While Platinum was known to the pre-Columbian people and discovered by modern man in the 1700's, it was not possible to produce the metal in quantity or work with it until the advanc...

We get a sample from the side of the road and extract precious metal from it.

In this video we pit the precious metal of platinum against various common chemicals. Turns out the platinum is resistant to hydrochloric acid, nitric acid and sulfuric acid. But it can be tarnished by molten sodium hydroxide.

http://illuminatisilver.com http://facebook.com/illuminatisilver Platinum vs Gold Update 2016 Today is Monday 12th September 2016 and we are providing our views on the case for and against Platinum. Since 1st January 2016 Platinum has risen by some 22% compared to 25% for gold and 39% for silver With Platinum currently priced at $1062 per ounce compared to gold which today stands at $1328 one can see that gold is trading at a 25% premium to platinum. Many investors find this strange, especially when one considers that historically, platinum often sells for about 1.5 times the value of gold per ounce. So what do we conclude from all this we hear you ask? Well as always it’s never clear cut, otherwise we would all be taking out call or put options and retire to the Maldives or some oth...
Bout time, they opened up the do' for Z-Ro
Cause I've been dropping hits, since ten years ago
Trying to do it legal, and not slang yayo
If I can't get it legal, to the corner I go
I never took pride, in slanging cocaine
Never could get a job, but needed some mo' change
C.d.'s wasn't selling, because I had no name
Nothing but a t-shirt, no piece no chain
Too many times, I was ready to give up
Run up in a bank, and say this is a stick-up
Put my pain on records, and record sales picked up
The tears I done shed, led me to the big bucks
2000 and 4, I ain't broke no mo'
Cause God is my life jacket, when I sink solo
I went to a hundred thousand, from a whole fo'
So all you haters hate me, as I make a little mo'
[Hook]
I'm going platinum this time, (this time-this time)
I think you fellas, better respect my mind (mind-mind)
I'm here to collect my pennies, my nickels and my dimes (my dimes-my dimes)
And ain't nobody gonna block out my shine (shine-shine)
[Z-Ro]
They got me living in a '56, Mass L
My locker full of commsary, and my fan mail
My city saying Z-Ro, what you gon do when you get out of jail
I can't do no mo' pyrexes, no mo' scales
Trying to make a million dollas, off my melody
Couldn't see it coming, so I caught a state-jail felony
F-1 bunk twelve, there resides the stars
Special thanks to love, cause "I Hate U Bitch" climbed me to the top of the charts
Being free, is like being on lock
Niggaz still kick it with ya, but try to get some of what ya got
I ain't never seen, so many feminine men
Swear to God they holding in the world, but ain't nobody seeing dividends
That ain't the life of me, I had to get it
Might not be rich in the present, but I'ma be rich in a minute
Cause I got three Cuzos sitting up high, rolling 24's
Screaming A.B.N. get in the do', waiting for Ro
[Hook]
[Z-Ro]
Jealousy and envy, play a major role
Everytime a playa, try to get his pockets swoll
Somebody said I did this, and said I did that
Even told homicide, I pushed the homie's wig back
They don't wanna see, a nigga make it out of poverty
When will they realize, God is running with me ain't no stopping me
Probably never will, so keep on trying
You can clip my wings, but I see happiness in the sky so I'ma keep on flying
Until I find, a rested place
So many battle scars, blood on my chest and face
Whether I'm working or rapping 24/7, me and Satan be scrapping
He want my soul, but I ain't gon let it happen
Even if I lose my life, trying to chase my dream
Whoever do me, gon have hell when they face my team
I got them same three Cuzos holding me down, if I ain't coming back
