Two-Product Mass Balance

Calculate concentrate recovery, yield, and stream mass flow rates from feed (f), concentrate (c), and tailings (t) assays.

💡 Engineering Knowledge PrimerIn mineral processing, two-product mass balancing uses solid assay conservation (Feed, Concentrate, Tailings) to calculate valuable mineral recovery and yield without needing physical stream flow meters. In plant operations, a higher recovery with stable concentrate grade indicates optimal flotation or gravity separation performance.
CALCULATION SCOPE — Deterministic calculation within the published assumptions. Independently verify all design decisions and project-specific code requirements.

Technical Methodology & Engineering Principles

GOVERNING EQUATION
Yield Y = (f - t) / (c - t) × 100% Recovery R = (c / f) × Y C = F × Y / 100 T = F - C K = 100 / Y
Assumptions & Scope

Steady-state operation, representative sampling, no unmeasured material accumulation or stream losses.

Operating Range & Boundary

Assays must satisfy: c > f > t.
