Grade & Recovery Balance Check

Check mass pull and separation efficiency using a measured recovery at the selected concentrate grade.

💡 Engineering Knowledge PrimerThe Grade-Recovery curve represents the fundamental metallurgical trade-off in mineral separation: pushing for higher mineral recovery inevitably dilutes concentrate grade. Separation Efficiency (E = Recovery - Mass Pull) identifies the economic optimum operating point.
OPERATING LIMITS — Balance check only; recovery must come from measured testwork at the selected concentrate grade.

Technical Methodology & Engineering Principles

GOVERNING EQUATION
Mass Yield Y = (Feed Grade / Concentrate Grade) × Recovery Separation Efficiency E = Recovery - Mass Yield
Assumptions & Scope

Recovery is measured/testwork data at the selected concentrate grade. Grade and target grade alone cannot generate a recovery curve.

Operating Range & Boundary

Use finite, physically meaningful inputs within the stated operating assumptions.
