Mine Call Recovery Calculator
Compare actual independently called versus delivered matched dry ore rather than recovery-corrected contained-metal MCF. Signed reductions/increases retained. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
A mine-call dry-ore reconciliation compares independently matched baseline and after-stage inventories.
A mine-call dry-ore reconciliation compares independently matched baseline and after-stage inventories.1
A ratio and signed change preserve both reductions and increases.
When to use Mine Call Recovery 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 Mine Call Recovery Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedMineCallRecoveryBaseline, observedMineCallRecoveryAfter, using the field meanings and rules below, then run the tool.
- Read observedMineCallRecoveryRatios, signedMineCallRecoveryChanges. 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 |
|---|---|---|---|
| observedMineCallRecoveryBaseline | Observed mine call recovery baseline | list of number | Required |
| observedMineCallRecoveryAfter | Observed mine call recovery after | list of number | Required |
Use aligned baseline values>0 and after values≥0 on a matched basis. Return after/baseline and after−baseline per record, without clipping ratios at one. The tool does not derive contained metal from assays or determine stage boundaries.
ratio_i=after_i/baseline_i; change_i=after_i−baseline_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedMineCallRecoveryRatios | Observed mine call recovery ratios | list of number |
| signedMineCallRecoveryChanges | Signed mine call recovery changes; preserve the subtraction order and sign defined in the mechanics | list of 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.
