Enrichment Ratio Calculator
Audit observed matched-trial enrichment without solving concentrate mass balance or pooling trials as physical products. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Enrichment compares concentrate assay with feed assay within a matched trial.
Enrichment compares concentrate assay with feed assay within a matched trial.1
A feed-weighted summary uses represented feed mass rather than treating all trials equally.
When to use Enrichment Ratio 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 Enrichment Ratio Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedMatchedFeedAssayFractions, observedMatchedConcentrateAssayFractions, observedTrialRepresentedFeedTonnes, using the field meanings and rules below, then run the tool.
- Read observedTrialEnrichmentRatios, feedWeightedAssayEnrichmentRatio. 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 |
|---|---|---|---|
| observedMatchedFeedAssayFractions | Observed matched feed assay fractions | list of number | Required |
| observedMatchedConcentrateAssayFractions | Observed matched concentrate assay fractions | list of number | Required |
| observedTrialRepresentedFeedTonnes | Observed trial represented feed tonnes | list of number | Required |
Use aligned feed assay fractions>0≤1, concentrate fractions [0,1] and represented feed tonnes≥0. Require positive total represented feed metal. Return each concentrate/feed ratio and Σ(concentrateAssay×feedTonnes)/Σ(feedAssay×feedTonnes). Ratios below one are allowed.
ratio_i=c_i/f_i; weighted=Σc_i m_i/Σf_i m_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedTrialEnrichmentRatios | Observed trial enrichment ratios | list of number |
| feedWeightedAssayEnrichmentRatio | Feed weighted assay enrichment ratio | 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.
