Separation of Eu and Y from Phosphor Dust

Purpose

  • Create a process that is technically, economically, and environmentally sustainable to produce purified yttrium oxide and purified europium oxide.
  • Produce a consistent, salable output from waste phosphor dust
  • Minimize waste generation
  • Increase materials independence

Deliverables

  • Perform physical separation process to improve the project economics
  • Develop a hydrometallurgical process that yields salable, purified yttrium oxide and europium oxide from semi-pure mixed rare earth oxides
  • Conduct an economic analysis using Monte Carlo simulation that validates the process is economically feasible
