Blended mineral grade by mass
Estimate the mass-weighted grade of two lots with stated masses and grades.
Method and scope
Blend grade = (m₁g₁ + m₂g₂)/(m₁ + m₂).
Use blended mineral grade by mass for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Lot 1 mass — kg, g, t
- Lot 1 grade — 1
- Lot 2 mass — kg, g, t
- Lot 2 grade — 1
SOURCE AND LIMITS
Assumptions: Grades use the same analyte and mass-fraction basis. The two lot masses and grades represent the material actually blended.
Limitations: Sampling, moisture, processing, and heterogeneity are not modeled.
