What type of mining is used for rare earth metals?
Most rare-earth ores are mined by conventional open-pit methods in which rock is broken by blasting, loaded onto trucks with large shovels, and hauled to a concentration plant. Concentrating is by physical separation of the REE-bearing minerals from all other minerals in the rock.

What is the hardest ore to find in the world?
Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
