Now, 1 tonne of REM supplied to the mill contains 0.185 t (185 kg) of neodymium. With 59 tonnes of ore mined per tonne of REM, the amount of ore mined and supplied to the mill to get 1 tonne of neodymium is 59/0.185 = 318.9 tonnes. The mill only recovers 50% of the metal supplied to it.

Since crushed stone has a unit weight of around 2700 lbs/yd³, and 1 ton is equivalent to around 2205 lbs. we can say that a ton of crushed stone is about 0.82 yd³ in volume. We obtain that value by dividing the weight in pounds by the unit weight in pounds per cubic yard: 2205 lbs / 2700 lbs/ yd³ = 0.8166 yd³ ≈ 0.82 cubic yards.

Diamond Mining and Prospecting. Diamond is unusual as a target for mining because it is found in igneous/explosively emplaced rocks, and the diamonds are carried up with these rocks from the Earth's mantle. Apparently the depths are somewhere in the vicinity of 160 km (100 miles) below the Earth's surface. The diamonds can then be mined in this ...

Now a cubic yard is 27 cubic feet, so if we divide 9,362,000 by 27, we get 346,740 cubic yards. We still must subtract the overburden, and on mine it is a a foot deep, so I must subtract 301,000 cubic feet, or 11,148 cubic yards. So that means I have 335,592 cubic yards of gravel in the ground.
