The Geology of Rare Earth Elements

When a rare-earth deposit undergoes such weathering, it may be enriched in rare earth elements in concentrations of economic interest. A particular type of REE deposit, the ion-absorption type, is formed by the leaching of rare earth elements from seemingly common igneous rocks and fixing the elements onto clays in soil.

Metals and Ores ~ Learning Geology

Iron constitutes only about 6.2% of the continental crust's weight but makes up about 30% to 60% of iron ore. The concentration of a useful metal in an ore determines the grade of the ore the higher the concentration, the higher the grade. Whether or not an ore of a given grade is worth mining depends on the price of metal in the market.
