Of the nine precious metals, platinum is considered to be the most abundant and is estimated to be. All other metals are ranked from highest to lowest in terms of abundance. Rhenium, ruthenium, rhodium, iridium, osmium, gold, palladium and silver are the order in which they appear. The most valuable of all precious metals is rhodium.
This silver-colored metal is extremely rare and is commonly used for its reflecting properties. It has a very high capacity to tolerate corrosive objects without being affected and has a fairly high melting point. The largest producers are Canada, Russia and South Africa. Platinum is next on the list of precious metals and is known to be dense and non-corrosive.
It has become popular because it is very malleable. This metal is no different from palladium in the way that it resists hydrogen in large quantities. . In the field of electronics, it is quite popular and is used to effectively plate electrical contacts.
In the platinum group, iridium is the extreme member. There is a very high melting point for this white-type metal and it is considered to be very dense. Iridium is a by-product of nickel mining and is processed from platinum ore. This metal is blue-silver in color and is one of the densest elements on Earth.
This harder and more brittle metal has a very high melting point. Osmium is mainly produced in South America, North America and parts of Russia. Used for hardening, it allows platinum for filaments and electrical contacts. Precious metals come in a variety of different shapes and sizes; gold and silver are the most common.
The list of expensive precious metals and the figures mentioned below have been compiled from various sources on the web, such as 911Metallurgist %26 Gold Investments. It can be found in the Earth's crust in its purest elemental form, as an alloy with gold and other precious metals, and in minerals such as chlorargyrite and argentita. However, most of the world's silver is produced as a by-product of refining gold, lead, copper and zinc. Rhenium is considered to be one of the rarest metals in the Earth's crust and has the third highest melting point and the second highest boiling point of all the stable elements.
Rhenium was discovered in 1908 and was named after the Rhine River in Europe. It was also the penultimate stable element found, just before hafnium. Osmium is a hard blue-white transition metal from the platinum group that can be found as a trace element in platinum alloys and minerals. Iridium is a hard, silver-white transition metal that is considered to be the second densest metal on Earth.
Iridium was discovered in 1803 by Smithson Tennant, who named the precious metal after the Greek goddess Iris because its striking salts resembled all the colors of the rainbow. Belonging to the platinum group, ruthenium is a rare transition metal that was discovered by the Russian-born scientist Karl Ernst Claus in 1844 at Kazan State University. He named the element Ruthenium in honor of Russia, since Ruthenia is Latin for Rus. Ruthenium is most commonly found in minerals with other metals from the platinum group in the mountains of North and South America.
It is widely used in various electronic devices and equipment. The third most expensive precious metal in the world is gold. In its purest form, gold can is a bright yellow metal, dense, soft, malleable and ductile and is one of the least reactive chemical elements on Earth. Gold is often found in its native free elemental form, nuggets or grains in rocks, veins and alluvial deposits.
China continues to produce the largest amount of gold, with an estimate of 440 tons per year. Discovered in 1803 by English chemist William Hyde Wollaston, palladium was named after the asteroid Pallas. It is part of the platinum group along with platinum, rhodium, ruthenium, iridium and osmium, which have similar chemical properties; however, palladium has the lowest melting point and is the least dense of all. The most common use of palladium is in catalytic converters, which are used to convert up to 90% of all harmful gases in automotive exhaust gases into less harmful substances.
The title of the most expensive precious metal in the world goes to Rhodium. Rhodium is a member of the platinum group and a noble metal. It was first discovered by William Hyde Wollaston in 1803 and got its name because of the pink color of one of its chlorine compounds. Like the world's second most expensive precious metal, palladium, about 80% of the world's rhodium is used as one of the catalysts for a three-way catalyst in cars.
Platinum has made a name for its malleability, density and non-corrosive properties. This metal is also similar to palladium in its ability to withstand large amounts of hydrogen. Nor do you need that much to find gold with our recommended cheap metal detectors that help you find metals such as gold for a fraction of the cost of traditional equipment. One of our most popular products for gold miners are rock shredders, which make it possible to extract gold from the earth from rocks.
This member of the platinum metals retains many of the group's characteristics, such as hardness, rarity and ability to withstand external elements. He is the most extreme member of the platinum group. This whitish metal has a very high melting point, is one of the densest elements that exist and stands as the most resistant metal to corrosion. Iridium is processed from platinum ore and as a by-product of nickel mining.
One of the densest elements on Earth, osmium is a blue-silver metal. This very hard and brittle metal has an extremely high melting point. One of the densest metals, with the third highest melting point. Rhenium is a by-product of molybdenum, which is essentially a by-product of copper mining.
Metals play a key role in our daily lives. This metal is used as a catalyst in the chemical industry and is used to coat optical fibers, optical mirrors and headlight reflectors. This identifiable metal occupied the throne in commodity prices for decades until it was overtaken by gold. This precious metal is used in jewelry and many industrial applications, including fuel cells, dental work, electronic components, medicine, glass and oil.
This metal is less well-known and is a member of the platinum family of precious metals. It is popular for its ability to increase hardness and strength when added as an alloy to palladium and platinum. Ruthenium is also used in the medical and chemical industries. Another member of the platinum family and the most extreme, this metal has a very high melting point and is the metal most resistant to corrosion.
Iridium is a by-product of nickel mining and is also processed from platinum ore. Although it has many uses, it is mainly used as a hardening agent in platinum alloys. These metals are often extracted from the same mineral deposits and are some of the most valuable metals found on Earth. The properties, industrial uses, scarcity and cost of acquiring each of the metals listed below contribute to their value, making them an attractive investment.
However, we were quickly surprised by the amount of these precious metals used in many everyday products. This precious metal is extremely rare and can best be described as a hard, corrosion-resistant, silver-white inert transition metal. While it has common uses, it is not a practical metal to manufacture due to its toxicity and high melting point. Ruthenium (Ru) is a rare metal used as an alloying agent to harden other metals, such as platinum and palladium.
Silver has the best thermal and electrical conductivity, as well as the lowest resistance to contact among other precious metals. .
