Mining Recovery Percentage
Reconcile matched ore inventory, recovered ore and separate diluent; excludes processing recovery and requires comparable dry-tonnage definitions.
Description
Mining recovery compares extracted ore with a matched planned ore inventory.
Mining recovery compares extracted ore with a matched planned ore inventory. Diluent increases mined total but should not be counted as recovered ore.
The tool returns oreRecoveryPercent (ore recovery percent); oreLossTonnes (ore loss tonnes); minedTotalTonnes (mined total tonnes). Input measurements and model parameters are supplied by the caller; the tool computes the stated summary rather than acquiring those measurements.
When to use Mining Recovery Percentage
Use Mining Recovery Percentage when you already have plannedOreTonnes, extractedOreTonnes, extractedDiluentTonnes and want oreRecoveryPercent, oreLossTonnes, minedTotalTonnes. This is useful for checking a supplied calculation, documenting a measurement convention, or comparing observations prepared on the same basis.
How to use Mining Recovery Percentage and understand its results
- Enter plannedOreTonnes, extractedOreTonnes, extractedDiluentTonnes using the field table below. Match the units, ordering and data boundaries described in the calculation.
- Run the tool after checking the stated bounds and matching paired observations or categories. A malformed request gives a tool error rather than a usable measurement.
- Read oreRecoveryPercent, oreLossTonnes, minedTotalTonnes. Use the calculation and interpretation below to distinguish amounts, ratios, signs and decision flags where applicable.
- Review the supplied parameters and assumptions before using the result in a report or comparing it with another observation.
| Input field | Meaning | Value type and bounds | Requirement |
|---|---|---|---|
| plannedOreTonnes | Planned ore tonnes | number | Required |
| extractedOreTonnes | Extracted ore tonnes | number | Required |
| extractedDiluentTonnes | Extracted diluent tonnes | number | Required |
Use positive planned ore and nonnegative extracted ore and diluent. Extracted ore may not exceed the matched plan.
oreRecovery% = 100×extractedOre/plannedOre; loss = planned−extractedOre; total = ore+diluent The symbols refer to the supplied quantities or generated values described above; unit conversions and comparison boundaries follow the stated implementation.

}Limitations and assumptions
Inventory boundaries and ore/diluent classification are supplied. This is mining recovery, not plant metal recovery.
Numerical inputs must be finite. The tool checks its declared input shape and calculation constraints; those checks do not verify the quality, calibration or representativeness of the supplied observations.
Alternative or Complementary methods
Recovery Percentage: Balance metal recovery across multiple disjoint dry product streams; unlike analytical spike recovery, this checks both process mass and contained-metal feasibility. Ore Tonnage: Sum block ore tonnage from bank volumes, densities and modeled ore fractions; no resource classification or geological continuity is inferred.
Methodological background: Material balance in mineral processing.1
