A precious metal is a naturally occurring rare mineral chemical element with high economic value. Chemically, precious metals tend to be less reactive than most elements. They are usually opaque and have a strong luster. Precious metals have historically been especially important in the currency industry, but are now primarily considered an investment and a commodity with many uses. There are distinctive symbols for those metals such as gold, silver, platinum and palladium.
The most precious metals used in coin making are gold and silver. Although both have wide uses in industry they are better known for their uses in jewelry. Precious metals also include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum. Each mineral has a different value, this value mostly depends on the rarity of the mineral, how difficult it is to extract it, and the properties of the mineral itself.
Here is a list of the most expensive minerals in the world in order, illustrated with pictures as follows:
1 – rhodium metal
-
- Rhodium metal – the most expensive metal in the world
Rhodium is the most expensive metal in the world
is one of the rarest minerals on earth
the largest producer of this The metal is South Africa, Canada and Russia
It is also characterized by its ability to withstand Corrosion and high temperatures
The price of a gram of rhodium is
Iridium comes in second place
Iridium is a member of the platinum group and is one of the most Density
Moreover, it is one of the most corrosion-resistant metals and has a melting point VERY HIGH
Because of these properties, this metal is used in many industries Including electronics, cars and medicine
Metal Palladium (3rd rank)
The price of palladium was lower than gold between the two years 2001 And 2018 But since February , Forbes magazine reported that palladium is now worth more than gold
This metal is rare Approximately 3283 once compared to gold in nature, and that is the reason for its high price
This metal is commonly used in car catalytic convertersThe largest producers of palladium are Russia, Canada, the United States and South Africa
4 – rhenium metal
Rhenium – the fourth most expensive metal in the world
Rhenium is mined in Chile, Kazakhstan and the United States.
It is one of the densest minerals.
has the third highest melting point among metals.
for this Reason It is added to nickel-based superalloys as a way to improve its high-temperature strength
(Rhenium is also used in filaments, high-temperature turbine engines, and electrical contact materials. This metal has a silvery white appearance. dollars per ounce
5 – the metal of gold
Gold comes in fifth place
Gold is described as one of the most sought-after minerals in the world as an investment in The first is next to the jewelry industry, where it retains its value and may rise even in times of economic and political instability. (The countries from which the most gold is extracted include South Africa, China, the United States, Australia and Russia
- The most common use of gold of various calibers is in jewelry, although it has many other uses.
6 – platinum metal
Platinum metal – sixth place
- Some of its uses only include jewelry, navigation and dentistry
One of the most useful benefits of platinum is its malleability
It is one of the heaviest minerals and is produced in South Africa, Canada and Russia. Previously
This metal was more valuable than gold, prices change and vary daily from time to time Platinum is more valuable than gold, and sometimes gold is more valuable than platinum
- The versatility of platinum is what makes it one of the most widely used precious metals in the world. For a scientist
7 – Ruthenium metal
Ruthenium metal – seventh place
Ruthenium is a member of the platinum family
It is mainly mined in Canada, Russia, North America and South America
Distinguishing properties of ruthenium: its hardness and its ability to withstand external factors
It is one of the rarest minerals on the planet
Ruthenium is often added to platinum to increase its hardness and resistance
Also, it is sometimes added To palladium as an alloy to make it stronger
The price of ruthenium is up 10 dollars per ounce
8 – Osmium Metal
Osmium metal – the eighth most expensive mineral in the world
-
- It is a rare mineral with a high density, most of which is mined From North America, South America and Russia
This metal is very difficult to process because it is a hard metal High Melting Point
There are many different uses for this metal, but the purposes most Widely used in hardening alloys, electrical conductors, and threads.
9 – the metal of silver
Silver metal – the ninth most expensive metal in the world
The largest producers of silver in the world are China, Mexico and Chile.
Of all the metals, silver has the best thermal and electrical conductivity along with the lowest contact resistance
This means that it is one of the most efficient metals in electronics
Its uses include jewelry, photography, dentistry, batteries, coins, and electrical circuits
M Aden Indium – the tenth most expensive metal in the world
Indium is mined mainly in Japan, South Korea and China
It is often used by electronic manufacturers due to its excellent conductivity
It is also used in painting aircraft engines
The most important things that are done Its manufacture using indium includes semiconductors, electrical conductors, and corrosion-resistant mirrors.
