Why am I not surprised that China’s Rare Earth Mining complex
is powered by coal mines
feeding Coal Fired Electric Generating Plants.

Meanwhile, in the United States
the University of Kentucky Mining Engineering Department is getting grants to extract Rare Earth Minerals from the waste piles of coal cleaning plants in Western Kentucky.

Duke Power Company has been sponsoring research to extract Rare Earth Minerals from the ash from coal fired electric generating plants that burned Appalachian region coal.

The world’s first large Rare Earth Minerals Mine at Mountain Pass CA near the Nevada border still struggles to reopen because its tailings ponds have small concentrations of Uranium and Thorium.
