Platinum Commodity Add to watchlist Trade Now. News Mining. Kitco 4d. Newsfile 4d. This led him to believe he was working with a single metal, but in truth the ore still contained the yet-undiscovered platinum-group metals.

This led to inconsistent results in his experiments. At times, the platinum seemed malleable, but when it was alloyed with iridium, it would be much more brittle.

Sometimes the metal was entirely incombustible, but when alloyed with osmium, it would volatilize. This started what is known as the "platinum age" in Spain.

Platinum, along with the rest of the platinum-group metals , is obtained commercially as a by-product from nickel and copper mining and processing.

During electrorefining of copper , noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals.

If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities.

Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid.

Platinum is paramagnetic , whereas nickel and iron are both ferromagnetic. These two impurities are thus removed by running an electromagnet over the mixture.

Because platinum has a higher melting point than most other substances, many impurities can be burned or melted away without melting the platinum.

Finally, platinum is resistant to hydrochloric and sulfuric acids, whereas other substances are readily attacked by them. Metal impurities can be removed by stirring the mixture in either of the two acids and recovering the remaining platinum.

One suitable method for purification for the raw platinum, which contains platinum, gold, and the other platinum-group metals, is to process it with aqua regia , in which palladium, gold and platinum are dissolved, whereas osmium, iridium, ruthenium and rhodium stay unreacted.

The gold is precipitated by the addition of iron II chloride and after filtering off the gold, the platinum is precipitated as ammonium chloroplatinate by the addition of ammonium chloride.

Ammonium chloroplatinate can be converted to platinum by heating. The remaining The most common use of platinum is as a catalyst in chemical reactions, often as platinum black.

It has been employed as a catalyst since the early 19th century, when platinum powder was used to catalyze the ignition of hydrogen.

Its most important application is in automobiles as a catalytic converter , which allows the complete combustion of low concentrations of unburned hydrocarbons from the exhaust into carbon dioxide and water vapor.

Platinum is also used in the petroleum industry as a catalyst in a number of separate processes, but especially in catalytic reforming of straight-run naphthas into higher-octane gasoline that becomes rich in aromatic compounds.

PtO 2 , also known as Adams' catalyst , is used as a hydrogenation catalyst, specifically for vegetable oils. From to , the meter was defined as the length of a platinum-iridium alloy bar, known as the international prototype of the meter.

The previous bar was made of platinum in Until May , the kilogram was defined as the mass of the international prototype of the kilogram , a cylinder of the same platinum-iridium alloy made in The resistance wire in the thermometer is made of pure platinum e.

The NIST manufactured the wires from platinum bar stock with a chemical purity of The standard hydrogen electrode also uses a platinized platinum electrode due to its corrosion resistance, and other attributes.

Coins, bars, and ingots are traded or collected. It is used for this purpose for its prestige and inherent bullion value. Jewellery trade publications advise jewellers to present minute surface scratches which they term patina as a desirable feature in attempt to enhance value of platinum products.

In watchmaking , Vacheron Constantin , Patek Philippe , Rolex , Breitling , and other companies use platinum for producing their limited edition watch series.

Watchmakers appreciate the unique properties of platinum, as it neither tarnishes nor wears out the latter quality relative to gold.

During periods of sustained economic stability and growth, the price of platinum tends to be as much as twice the price of gold, whereas during periods of economic uncertainty, [74] the price of platinum tends to decrease due to reduced industrial demand, falling below the price of gold.

Gold prices are more stable in slow economic times, as gold is considered a safe haven. Although gold is also used in industrial applications, especially in electronics due to its use as a conductor, its demand is not so driven by industrial uses.

In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king.

Platinum is used as an alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, dental prostheses, electrical contacts, and thermocouples.

Platinum-cobalt, an alloy of roughly three parts platinum and one part cobalt, is used to make relatively strong permanent magnets.

Platinum's rarity as a metal has caused advertisers to associate it with exclusivity and wealth. Platinum is considered a precious metal, although its use is not as common as the use of gold or silver.

It was the first British crown to be made of this particular metal. According to the Centers for Disease Control and Prevention , short-term exposure to platinum salts may cause irritation of the eyes, nose, and throat, and long-term exposure may cause both respiratory and skin allergies.

As platinum is a catalyst in the manufacture of the silicone rubber and gel components of several types of medical implants breast implants, joint replacement prosthetics, artificial lumbar discs, vascular access ports, etc.

The Food and Drug Administration and other institutions have reviewed the issue and found no evidence to suggest toxicity in vivo.

January Handbook of corrosion data. Ammonium Hexachloroplatinate IV. Inorganic Syntheses. Platinum is the natural choice for milestone jewelry, such as engagement rings and wedding bands, because it holds significant gemstones better than any other precious metal.

Diamonds set in platinum are also enhanced by the natural whiteness of the metal, whose glowing patina gets more beautiful with time. And unlike white gold, which retains its whiteness only by being plated with rhodium, platinum will never need re-plating.

Recognized as an element in the 18th century, scientists soon discovered that this unusual white metal, difficult to melt using traditional methods, was also nearly incorruptible by gases or chemicals making it thoroughly non-corrosive.

Platinum is also extremely dense.
