Most Valuable Metals That We Couldn’t Live Without
Our modern 21st-century lives are driven by metals. They can be found in the LEDs, magnets, electric motors, sensors, data storage and many other components upon which modern life relies. They power our mobility and energy generation, which is why there are hundreds of commercial applications for metals, with more uses being discovered each year.
While you are probably familiar with metals such as gold, silver or platinum, they aren’t the most expensive. Most of the costliest metals belong to an obscure group known as the rare earth elements. They're given this name because they are almost always found bound together as a compound, and extracting an individual metal is a complicated, lengthy and expensive process. You can identify a rare earth element from its long, complicated name, such as dysprosium or neodymium. Some are abundant, while others are the rarest on the planet.
Rare earth metals are vital for low-emission technologies and power generation, such as electric cars and wind turbines. Global efforts to reduce emissions will continue to drive demand, especially in China, which mines almost all of the rare earth ores. This may lead to increasing prices. However, more exploration and new deposits could stabilize or even lower costs.
Some metals may appear to have relatively low kilogram prices, but keep in mind that sales of these metals (or their ores) are usually transacted in much larger quantities, even tons. These are the most valuable metals in the world.
