Deal with Rare earth metals

Rare and valuable metals of the Earth include a mix of rare earth elements and other precious or strategic metals that are important for technology, energy, and industry.
Platinum is a precious metal known for its rarity, resistance to corrosion, and excellent catalytic properties. It is widely used in jewelry, catalytic converters for vehicles, medical devices, and chemical industries. Platinum is more expensive than gold because of its scarcity and high industrial demand.
Uranium is a heavy metal mainly used as a fuel in nuclear power plants. It is valued for its ability to release large amounts of energy through nuclear fission. While not used in everyday products, uranium is strategically important for energy production and national security. Its handling is strictly regulated due to radioactivity.
Lithium (often mistakenly called “lithanium”) is a lightweight metal crucial for modern rechargeable batteries. It powers smartphones, laptops, electric vehicles, and energy storage systems. The growing demand for clean energy has made lithium one of the most economically important metals today.
Californium is an extremely rare, synthetic radioactive metal that does not occur naturally on Earth in usable amounts. It was first discovered in 1950 by scientists at the University of California, Berkeley, which is how it got its name. Californium is produced artificially in nuclear reactors by bombarding lighter elements, such as curium, with neutrons.
Despite its rarity, californium has important practical uses. One of its most valuable isotopes, californium-252, is a powerful neutron emitter. It is used in starting nuclear reactors, detecting gold and silver ores, inspecting metal fatigue in aircraft, and in certain cancer treatments. Because it is extremely difficult to produce and highly radioactive, californium is one of the most expensive metals in the world, with its cost reaching millions of dollars per gram.
Among the Most expensive metals on Earth are rhodium, iridium, and palladium, which are extremely rare and used mainly in advanced industrial applications, especially in electronics and catalytic converters. Their high price comes from limited supply, complex extraction, and strong global demand.
