rare earths crushing

South Australia becoming the 'Holy Grail' of the rare earths space

The main ore bodies lie between 5m and 30m from surface, so the rare earths can be extracted by open cut mining followed by heap leaching. While these clays account for only 2.9% of China's total rare earth reserves, they are vital to that country; between 1988 and 2007, the clays accounted for 26% of total REE production, rising to 35% in 2009.
