The Mohs hardness of uraninite, the primary ore of uranium, is 5 to 6. This mineral is commonly called pitchblende, and is largely composed of oxides of uranium. Mohs scale is usually applied to minerals, and not to "pure metals" like uranium. Use the link below to check facts and learn more.
Uranite is not correct, if you mean URANINITE, it is ranges 5-6 hardness.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
It's called the Ore
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
Azurite has a hardness of 3.5 to 4 on the Mohs hardness scale.
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
The hardness is 3-4 on Mohs scale.
Nickel has a hardness of 4 on the Mohs scale.
Dolomite has a hardness of 3.5-4 on the Mohs scale of hardness.
The Mohs scale is used to determine the relative hardness of minerals.
Aluminum Oxide is roughly 8.5 - 9.0 on the hardness scale.
This scale was proposed by the Austrian geologist Friderich Mohs.
