Mining Dilution Percentage Calculator
Extract actual moisture-corrected mining dilution inventory, dry diluent/(ore+diluent), not forward assay mixing or assumed equal moisture. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Mining dilution on a dry-mass basis separates recovered ore and diluent after moisture corrections.
Mining dilution on a dry-mass basis separates recovered ore and diluent after moisture corrections.1
Ore and diluent can have different dry fractions.
When to use Mining Dilution Percentage Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Mining Dilution Percentage Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedRecoveredWetOreTonnes, observedOreDryFractions, observedWetDiluentTonnes, observedDiluentDryFractions, using the field meanings and rules below, then run the tool.
- Read observedDryDiluentFraction. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedRecoveredWetOreTonnes | Observed recovered wet ore tonnes | list of number | Required |
| observedOreDryFractions | Observed ore dry fractions | list of number | Required |
| observedWetDiluentTonnes | Observed wet diluent tonnes | list of number | Required |
| observedDiluentDryFractions | Observed diluent dry fractions | list of number | Required |
Use aligned nonnegative wet ore and diluent tonnes with respective dry fractions [0,1]. Sum wet×dryFraction separately, require their combined dry total>0 and return dry diluent/(dry ore+dry diluent).
dilution=Σ(diluentWet×diluentDryFraction)/[Σ(oreWet×oreDryFraction)+Σ(diluentWet×diluentDryFraction)] Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedDryDiluentFraction | Observed dry diluent fraction; dimensionless fraction, not a percent | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
