The trial targeted copper losses in rougher tailings, specifically in the coarse (>212 μm) and fine (<45 μm) size fractions, where conventional flotation is less efficient. By validating the copper recovery at these size extremities, the trial provided the metallurgical and economic justification for advancing the project toward full-scale implementation.

Technical Highlights:

• Superior Metallurgical Performance: The pilot consistently exceeded all headline targets, achieving up to
  56% copper recovery, a product upgrade ratio > 6.0, and a mass pull of ~8%.
• Competitive Differentiation: Results validated the simplicity of the NovaCell™ design; high-value minerals
  were captured across all particle sizes in a single device, eliminating the need for upfront classification or
  separate fines flotation circuits required by competing technologies.
• Coarse Particle Recovery: Mineralogical analysis confirmed the system successfully recovered coarse, poorly
  liberated particles with <30% surface exposure, proving a critical capability for Coarse Particle Flotation (CPF)
