What are Rare Earth Minerals from Coal?

Rare earth minerals (REMs) are a group of 17 chemically similar metallic elements indispensable for modern technologies, ranging from smartphones and electric vehicles to defense systems. Traditionally, these minerals are extracted from specific geological ore bodies, a process that can be costly and environmentally intensive. However, research has increasingly focused on unconventional sources, with coal and its byproducts, particularly coal ash, emerging as a significant potential reservoir. Coal seams absorb and concentrate rare earth elements from the surrounding rock over geological time. Consequently, the combustion of coal results in these elements becoming concentrated in the resulting fly ash and bottom ash. Extracting ‘rare earth minerals from coal’ refers to the processes developed to recover these elements from these coal combustion residuals (CCRs). This approach offers a compelling prospect: utilizing a readily available industrial waste product to source critical materials, potentially reducing the environmental footprint associated with traditional mining and processing. As technology continues to advance, the demand for REEs is soaring, making the exploration of sources like coal ash increasingly vital for ensuring supply chain security, especially as we anticipate the needs of 2026.

The Concentration of Rare Earths in Coal Deposits

Coal seams act as natural concentrators for rare earth elements (REEs) due to their geological formation processes. Over millions of years, groundwater circulating through sedimentary rocks can leach REEs, which are then adsorbed by the organic material in coal beds. This process leads to concentrations of REEs in coal that can, in some cases, be comparable to or even exceed those found in traditional rare earth ore deposits. Elements such as lanthanum, cerium, neodymium, and yttrium are commonly found. When coal is burned in power plants, most of the organic material is combusted, leaving behind the inorganic mineral matter, including the concentrated REEs, primarily in the fly ash and bottom ash. The concentration levels can vary significantly depending on the specific coal basin, the geology of the surrounding rock formations, and the coalification process. Identifying coal deposits with high REE content is the crucial first step in developing this unconventional resource stream, forming the basis for extracting rare earth minerals from coal for future industrial use by 2026.

Coal Ash as a Valuable Byproduct

Coal combustion residuals (CCRs), commonly known as coal ash, are generated in massive quantities by coal-fired power plants. Historically, this ash has been disposed of in landfills or ponds, posing potential environmental risks if not managed properly, including groundwater contamination. However, CCRs also represent a significant, largely untapped resource of valuable materials, including rare earth elements (REEs), along with others like germanium, gallium, and vanadium. The concentration of REEs in some coal ashes can reach levels that make their extraction economically viable using emerging technologies. Developing efficient and cost-effective methods to recover these elements from coal ash presents a ‘waste-to-wealth’ opportunity. This approach not only provides a source of critical minerals but also addresses the environmental challenge of coal ash disposal, aligning with circular economy principles and sustainability goals that will be increasingly important leading up to 2026.

Various acids, such as sulfuric acid or hydrochloric acid, are commonly employed. The effectiveness of leaching depends on factors like the type of acid used, its concentration, temperature, and the duration of contact with the ash. Following leaching, the liquid solution containing dissolved rare earths must be separated from the solid residue. Subsequently, sophisticated separation techniques are employed to isolate individual rare earth elements from each other, as they often occur in mixtures. These techniques can include solvent extraction, ion exchange chromatography, or precipitation methods. Developing efficient, cost-effective, and environmentally friendly leaching and separation processes is key to making the extraction of rare earth minerals from coal economically feasible and scalable for industrial use by 2026.

Innovations in Processing and Purification

Beyond initial leaching and separation, further innovations are needed in the processing and purification of rare earth elements recovered from coal ash.
