Ucore Produces 99.99% Dysprosium via SuperLig(R)-One Pilot Plant - Seite 2

• Separation and Recovery of High Purity Dysprosium - Separation of high purity Dy from the PLS is particularly noteworthy in that the purity of the Dy is 99.99% versus all other metals in the PLS, including Terbium ("Tb") and Holmium ("Ho") ("Next Door Neighbors.") This achievement distinguishes the MRT process from other, less selective, technologies, such as solvent extraction, ion exchange and precipitation ("Legacy Separation Technologies") that require extensive processing to separate Dy from its Next Door Neighbors. The MRT process makes possible the separation of Dy directly from the Dy Sub-group without the need to separate other individual REE first. 99%+ of the Dy originally present in the PLS was recovered. This exceptionally high recovery rate maximizes value and reduces wastage.
  
  

• First Pilot Scale Demonstration of Green Chemistry Separation and Recovery of Rare Earth Elements - The SuperLig®-One Pilot Plant has successfully demonstrated a number of key advantages confirming an environmentally-friendly method for separation of individual REE:
  • No organic solvents used, minimization of chemical usage, and simplicity of Plant design and operation
  • Recovery of over 99% of the REE originally present in the PLS, resulting in essentially no loss of REE to the tailings, thereby generating maximum value
  • Separation of Gangue Metals early in the flow sheet negating the need for extensive downstream separations, that are necessary with Legacy Separation Technologies, resulting in lower capital and operating expenses along with less chemical usage and waste.
  • Highly efficient SuperLig® resin selectivities, thermodynamics and kinetics that reduce the number of separation stages needed to obtain high purity REE products, resulting in:
    • Lower metal inventory (working capital) costs due to faster processing time
    • Avoidance of generation of large amounts of waste and the associated societal negative externality effects due to environmental contamination that result from Legacy Separation Technologies
