Question

like do they seperate the ore from the coal or does it mean that they like mine it out of the ground?

I NEED HELP

and what about diamond extraction?

Answer 1

coal thing....gettin out from earth if i wasn't wrong

diamond thing.....making it from coal or gettin it from the mine (if there was ready made in the rocks)

Answer 2

The latter... they mine it out of the ground. Ore is purely a hard rock term where you have a precious mineral formed in hard rock. Like Aluminium (mineral) in Bauxite (ore). Coal is soft rock and has no ore. You extract/mine coal as it is found in the ground. Since they don't need to extract anything from coal (except perhaps methane gas) it is then sent to a washabilty plant for quality testing and shipped off to a power plant (in a nut shell). Diamond is hard rock so diamond extraction is where you extract diamond from the ore.
