What metal is the rarest?

The rarest metal on Earth is actually francium, but because this unstable element has a simple half-life. 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 allow gold to be extracted from rock dirt. 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 in existence and stands as the metal most resistant to corrosion.

Iridium is processed from platinum ore and as a by-product of nickel mining. Osmium (Os) is the densest metal in the world. It is also one of the rarest metals. Osmium is not harder than a diamond, but it is stiffer.

It is hard and brittle and has a blue-gray appearance when used in jewelry. Wollaston named the new metal rhodium, which has its roots in the Greek word for rose, rhodon, because of the reddish salts that dissolved in agua regia (aqua regia is a yellow-orange smoky liquid, named after alchemists because it can dissolve the noble metals gold and platinum).
