Within the first six months of effort, DOE-NETL FOA-1202 researchers demonstrated production of ≥ 2 wt% rare earth element (REE) pre-concentrates from coal-based materials.
In-depth technical work conducted by this program is hosted on EDX
The REE Program is focused on developing technologies for the recovery of REEs from Coal and Coal By-Products.
The 17-element group known as rare earth elements (REEs) provides significant value to our national security, energy independence, environmental future, and economic growth.
The Feasibility of Recovering Rare Earth Elements Program is currently focused on developing technologies for the recovery of rare earth elements (REE) and critical minerals (CM) from coal and coal-based resources. This R&D program consists of developing process and production technologies, environmental management, and field materials sampling and characterization, along with systems integration, optimization and efficiency improvements to produce REEs and CMs from coal and coal byproduct streams, such as coal refuse, clay/sandstone over/under-burden materials, power generation ash and aqueous effluents as acid mine drainage (AMD) and sludge.
Our nation’s vast coal resources contain quantities of REEs that offer the potential to reduce our dependence on others for these critical materials and create new industries in regions where coal plays an important economic role. The Department of Energy’s National Energy Technology Laboratory (DOE-NETL) REE-CM Program offers a pathway to improve the economics and reduce the environmental impact of a domestic coal-based value chain. The development of an economically competitive supply of REEs and CMs will assist in securing and maintaining our nation’s economic growth and national security.
Congressional Funding and Program Metrics
As a response to initially receiving Congressional funding in 2014 - to perform an assessment and analysis of the feasibility of economically recovering rare earth elements from coal and coal byproduct streams, such as fly ash, coal refuse and aqueous effluents - DOE-NETL’s REE Research, Development and Demonstration (RD&D) Program grew to over 30 active projects in 2018, which focused on:
Through its metrics, the REE Program fully supports FY19’s Congressional directive - to continue its external agency activities to develop and test advanced separation technologies and accelerate the advancement of commercially viable technologies for the extraction and recovery of rare earth elements and minerals from U.S. coal and coal byproduct sources.
