Join the Debate on Insitu Rare Earth Recovery
The McIlvaine Company believes insitu rare earth recovery from coal combustion will be much more economical than using flyash ponds and landfills as the source. The assertion is that coal fired boilers can generate rare earth feedstocks, 30 percent hydrochloric acid, and contaminant free ash, while avoiding many of the present problems of not removing HCl separate from the SO2.
There is a substantial factual basis for the assertion based on the operation of some coal fired plants and many municipal waste incinerators. Other than McIlvaine there is no other source who seems to have evaluated this opportunity. The University of Kentucky, Battelle, EPRI, Georgia Power, ACAA, Chinese researchers, suppliers of waste to energy systems with acid and metal byproduct sales and others will have insights which would help determine the efficacy of this option.
