Advancing Technologies through Assessments
EMRTAI supports technology developers by planning and conducting assessments using mining waste materials from legacy Superfund and abandoned mine land sites. With 100+ legacy mining and mineral processing sites within Superfund, sites and feedstocks can be identified for testing and subsequently advancing technologies to commercial scale. EMRTAI’s technology assessment framework is designed to generate integral data for technology advancement and decision-making.
Critical Mineral Recovery from Mining-influenced Water
Stalagmite Co.
Stalagmite is developing a critical mineral recovery technology to pull manganese, cobalt, nickel, and other transition metals selectively from waters and waste from the mining and oil & gas industries. The company's team is comprised of mining and oil & gas professionals based in Colorado. They're backed by the National Lab of the Rockies and Chevron Technology Ventures.
With the EMRTAI, a technology assessment is underway to recover cobalt, manganese, nickel, and REEs from acid mine drainage.
SiTration
SiTration is a spin-out of MIT enabling full value mining by efficiently recovering critical minerals from even the most dilute and complex streams. The company's core technology combines uniquely durable silicon filtration and electro-extraction stages to enable profitable and sustainable recovery of critical minerals including copper, cobalt, nickel, precious metals, and rare earth elements. SiTration’s technology can replace traditional resource-intensive mining processes and can be deployed to recover materials from traditionally inaccessible sources, including waste.
With the EMRTAI, they are developing a technology assessment focusing on recovery of copper.
REETerra
REETerra is a Pennsylvania-based company developing technologies that can extract rare earth elements from acid rock drainage and acid rock drainage treatment semisolids/solids. Their technology uses an ion-exchange chromatography method utilizing biological ligands, known as Lanmodulin (LanM). They have made great strides in advancing the capabilities of this method and have successfully recovered more rare earth elements with their process advancements.
With the EMRTAI, a technology assessment is underway to recover REEs from mining-influenced water.
Characterization of Critical Minerals in Solid Mining and Mineral Processing Waste
Hitachi
Hitachi High-Tech America provides a comprehensive suite of advanced analytical instruments -from XRF to optical emission spectroscopy (OES) to electron microscopy - designed for high precision and dependable performance in quality control, and industrial environments. Hitachi’s X-MET Series of handheld XRF is designed with hardware and software features that simplify analysis of earth metals, transition metals, rare earth elements (REE), and non-minerals between Mg (12) and U (92). The HHXRF is designed to be easy to operate in both the field and the lab allowing geochemists to optimize performance for site-specific materials.
With the EMRTAI, Hitachi will demonstrate instrument capabilities for measuring or quantifying concentrations of CM in solid mine waste from hard rock mining sites using the X-MET series of handheld XRF.
Recovery of Critical Minerals from Solid Mining and Mineral Processing Waste
Draslovka
Draslovka is a chemical technologies, products and services company creating value and improving sustainability in several industries, including mining, agriculture and manufacturing. Along with being the world’s largest producers of sodium cyanide, a chemical vital for gold mining, Draslovka’s proprietary technology, Glycine Leaching Technology, leaches metals in a more sustainable and economic manner, which is a major contribution to the gold mining industry.
