What is the strongest metal in the world?
tungstenIn terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi).
But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact.
Titanium, on the other hand, has a tensile strength of 63,000 psi..
What are heavy rare earths?
Heavy and light rare earth elements: The rare earth elements are often subdivided into “Heavy Rare Earths” and “Light Rare Earths.” Lanthanum, cerium, praseodymium, neodymium, promethium, and samarium are the “light rare earths.” Yttrium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, …
What country has the most resources?

Is Platinum better than gold?
Platinum is Stronger and More Durable Though both gold and platinum are strong and durable precious metals, platinum is the stronger and more durable of the two. For example, the prongs holding the center stone of a platinum engagement ring are less likely to break then those of a gold engagement ring.
What is the largest rare earth mine in the world?
Mountain Pass mineThe US is believed to hold 9% of the world’s rare earth reserves, estimated at 13Mt. The Mountain Pass mine, operated by Molycorp, in California is the country’s biggest rare earth producing mine.
Is Lithium a rare earth?
Although lithium is widely distributed on Earth, it does not naturally occur in elemental form due to its high reactivity. … According to the Handbook of Lithium and Natural Calcium, “Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations.

What is the most expensive substance on earth?
AntimatterAntimatter – $62.5 trillion per gram The most expensive substance on Earth. Production of one milligram of positrons costs about $25 million.
Where is rare earth found?
Today, the Indian and South African deposits still produce some rare-earth concentrates, but they are dwarfed by the scale of Chinese production. In 2017, China produced 81% of the world’s rare-earth supply, mostly in Inner Mongolia, although it had only 36.7% of reserves.
What are the rarest metals on earth?
In terms of abundance in the Earth’s crust, the rarest metals are; gold, platinum, osmium, iridium, palladium, ruthenium, rhodium, tellurium and rhenium. The first two most of us have heard of, what are the other seven, where are they found, and why do they matter?
