Low-cost selective precipitation circuit for recovery of rare earth elements from acid leachate of coal waste
Patent
·
OSTI ID:1859993
The present invention concerns a process of selective precipitation for the purpose of recovering rare earth elements from acidic media derived from coal and coal byproducts via two main steps of sequential precipitation and selective precipitation. An intermediary step of re-precipitation can be included to further increase RRE concentrations, as well as improve contaminant metal removal.
