:-The three most expensive minerals in the world

Francium

Among all the natural minerals, francium is the most expensive natural mineral ever, as only 100 grams of this mineral is worth billions of dollars. commercial.

This metal was first discovered by Marguerite Perey in 1939 at the Curie Institute in Paris. Currently, francium is the heaviest alkali metal ever, but also the least stable among the 101 elemental elements in the periodic table of chemical elements.

Francium is produced naturally as a result of the alpha dissociation of actinium with uraniumm metal, and is also made by bombarding thorium with protons.

 californium

The most expensive metal in the world is Californium, and although it is the most expensive metal, it actually receives little attention or use than most people, has a few select uses in the medical industry, and has extremely dangerous radioactivity, and this limits its main use for generating Nuclear Energy.

Californium is a man-made metal, its first appearance was in 1950, and its huge price is entirely due to its scarcity and production costs, and annually only 30 to 40 micrograms are manufactured, in laboratories only in Russia and the United States, and the price of a gram reaches 26 million pounds,

rhodium

Rhodium metal enters more practical applications than californium, which is the second most expensive metal in the world, and many people may think that gold or palladium is more expensive than rhodium, but its greater scarcity and broader scientific applications make it the second most expensive metal, and it was discovered in 1803, and the price of a gram of it about 148 pounds,

Rhodium is extremely rare, and gold is four times more abundant than it, and platinum is five times more abundant than it, and it is this rarity that puts it in second place in the table. Many industrial, due to its high reflectivity, is more used in lighting  ...and automobile production.

Palladium

Palladium is currently the third most expensive metal in the world, and the most expensive of the four major precious metals, gold, silver, platinum and palladium, was discovered in 1803, and is much rarer than platinum, and is used in large quantities in the manufacture of catalytic converters in cars, and the price per gram of it is 47 pounds,

californum

 .Californium, an element developed at the University of California in 1950, was made from curium and alpha particles, but only a few grams of the element were produced.

In today's world, only half a gram of californium is produced each year, which is why its price is so high, the primary use of the element is as a portable source of neutrons to detect other elements such as gold.

Californium is another radioactive element used primarily in research and tools used in the petroleum industry. A gram of californium can cost $27,252 per gram, making it significantly more expensive than lutetium, but less than francium. Items that are cheap

uranium

Uranium is an expensive synthetic metal, plus it is costly to isolate trace amounts of naturally occurring transuranic elements.

For example, based on the cost of acceleration time, manpower, materials, etc., the cost of californium is estimated to be around $2.7 billion per 100 grams. You can compare this price to the cost of plutonium, which ranges from $5,000 to $13,000 per 100 grams, .......depending on purity.
