12.8: Mining and Mineral Use

To extract the metal from the ore, the rock is melted at a temperature greater than 900 C, which requires a lot of energy. Extracting metal from rock is so energy intensive that if you recycle just 40 aluminum cans, you will save the energy equivalent of one gallon of gasoline.

Ore Minerals : What are Ore Minerals?

The ore quality, and density of a rock or metal ore, as well as its occurrence type, can directly affect the ore mining costs. It is therefore necessary to weigh the extraction cost against the metal value contained in the rock to determine which ore can be processed and which ore is too low a grade to be worth mining.

Where are Rare Earth Elements Found?

As we noted, although originally thought to be rare, many of the Rare Earth Element (REE) minerals are actually common in the Earth's crust. However, these elements rarely exist in pure form; they are usually found within other minerals, making them difficult to extract from the ore and costly to mine.
