eng.flotation-recovery-grade Calculator
Calculates flotation recovery and concentrate grade from feed grade, concentrate grade, and tailings grade using the metallurgical mass balance. Flotation recovery × concentrate mass / feed mass must balance — the metallurgical balance is the key audit check in mineral processing.
Inputs
Mass Feed T
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Grade Feed Pct
Reference formula or conversion factor shown for context.
Mass Conc T
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Grade Conc Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
metallurgical recovery R
Reference formula or conversion factor shown for context.
concentration ratio (grade upgrade)
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
metal recovered (t)
Reference formula or conversion factor shown for context.
tailings grade (%)
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
R = Mc·gc / (Mf·gf)
Reference formula or conversion factor shown for context.
performance classification
Category assigned based on where the computed value falls on a defined scale. Check which standard or guideline defines these boundaries.
