Yield & Mass-Pull Calculator
Calculate mass pull percentage and concentration ratio for magnetic separators, gravity concentrators, and screens.
💡 Engineering Knowledge PrimerMass Pull represents the mass percentage of total feed reporting to the concentrate stream. Low mass pull with high grade indicates selective separation (e.g., cleaner flotation or high-intensity magnetic separation), while excessive mass pull overloads downstream filters.
CALCULATION SCOPE — Deterministic calculation within the published assumptions. Independently verify all design decisions and project-specific code requirements.

GOVERNING EQUATION
Mass Pull % = (Product Mass / Feed Mass) × 100
Ratio of Concentration = Feed Mass / Product Mass
Assumptions & Scope
Clean mass flow measurements without water additions.
