Neotech Metals starts metallurgical process development for Hecla-Kilmer rare earth project with Dorfner Anzaplan
  • Neotech Metals began a metallurgical process development program with Dorfner Anzaplan to draft a preliminary processing flowsheet for the Hecla-Kilmer rare earth project in Ontario.
  • Ontario’s Critical Mineral Innovation Fund will partially fund work on a conceptual processing plant targeting rare earths, niobium, gallium, and purified phosphoric acid.
  • Program builds on 2025 testwork showing about 75% total rare earth oxide recovery, 89% phosphate recovery under mild leaching conditions.
  • Bench-scale work targets a high-grade apatite concentrate, a 60 kg bulk concentrate for hydrometallurgical testing, and impurity removal with REE precipitation.
  • Final report will outline recoveries, concentrate grades, reagent consumption, and next steps, including a potential pilot phase.
