Tailings Mass Calculator
Reconcile dry solids to external tailings after separately observed concentrate and exported/recycle stream boundary, not two-product assay tailings-grade inversion; internal recirculation already caller resolved. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
A tailings ledger needs a clear external boundary for feed, concentrate and exported or recycle material.
A tailings ledger needs a clear external boundary for feed, concentrate and exported or recycle material.1
This calculation accounts for separately measured dry streams after that boundary is established.
When to use Tailings Mass 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 Tailings Mass Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedDryFeedTonnes, observedDryConcentrateTonnes, observedIndependentDryRecycleTonnes, using the field meanings and rules below, then run the tool.
- Read observedNetExternalTailingsTonnes. 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 |
|---|---|---|---|
| observedDryFeedTonnes | Observed dry feed tonnes | list of number | Required |
| observedDryConcentrateTonnes | Observed dry concentrate tonnes | list of number | Required |
| observedIndependentDryRecycleTonnes | Observed independent dry recycle tonnes | list of number | Required |
Enter nonempty aligned nonnegative dry feed, concentrate and independent recycle/export tonnes. Return feed−concentrate−recycle per row and reject negative residuals. Internal recirculation must already be resolved by the supplied ledger.
externalTailings_i=feed_i−concentrate_i−recycle_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedNetExternalTailingsTonnes | Observed net external tailings tonnes | 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.
