Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| normalization | all cards | Exchange = attributable period quantity / D. Reconcile inventories and cancel internal transfers before aggregation. | cp_output; row-specific cp records | per 1 kg reference flow | |
| physical_balance | production | Independently weigh positive accepted net as-received gate total D kg excluding packaging/rejects/returns and matching stocks; every exchange divides by the same selected-product D. For measured wet-basis free-water fraction w,0 <= w <1, dry mass = D*(1-w); use a phase-preserving moisture method, not ignition loss that removes hydrate water or carbonate CO2. For measured dry-basis actual mineral/species fraction g, contained species mass = D*(1-w)g; state mineral formula/hydration and assay method. Barite is BaSO4, witherite BaCO3; assay reported as Ba converts to the declared species using molar-mass ratio only with confirmed speciation, not one interchangeable barium product. Fluorite is CaF2; as-F assay converts to CaF2 using M(CaF2)/(2M(F)) only when that F is confirmed in fluorite; fluoride-ion/other F species are separate. Boron assay as-B2O3 equivalent is not actual oxide: elemental B mass = B2O3-equivalent mass2M(B)/M(B2O3), preserving assay basis and without asserting a borate mineral purity. Natural H3BO3 dry fraction gH <=0.85 requires measured species and geological origin; as-B alone cannot establish H3BO3 if other borates are present. Identify kieserite/epsomite and retained hydration independently; neither crystal-water release nor sulfate assay establishes free water or pure MgSO4. Actual admitted calcination uses independent input/output weighing, phases, free/structural water, carbonate CO2 and dust balances; no unchanged hydrate mass, fixed yield or assumed conversion. Recovery uses matched input/output contained identified species after stock correction, not output grade alone. Reconcile feed solids, accepted grades, actual co-products, waste rock/tails/dust, thermal losses and stocks, plus fresh/recycled/evaporated/discharged water separately. No empirical purity, yield, reagent dose or utility intensity defaults. | Matched mass, volume, composition and stock measurements | Balance residual and uncertainty |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| representativeness | dataset | Use matching production and exchange periods, actual technology, geography and supplier state. Record startup, shutdown, seasonal variation and substitutions. | collection records |
| identity_and_ranges | all cards | Unresolved identities and missing independent range evidence remain explicit. Do not replace measurement by a guessed industry range or by missing-as-zero. | manifest review metadata |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| validate_reference | final_product | Verify 1 kg, positive D, product state, property/unit and every required qualifier. Each dataset fixes one product and route. | |
| validate_balance | site | Independently weigh positive accepted net as-received gate total D kg excluding packaging/rejects/returns and matching stocks; every exchange divides by the same selected-product D. For measured wet-basis free-water fraction w,0 <= w <1, dry mass = D*(1-w); use a phase-preserving moisture method, not ignition loss that removes hydrate water or carbonate CO2. For measured dry-basis actual mineral/species fraction g, contained species mass = D*(1-w)g; state mineral formula/hydration and assay method. Barite is BaSO4, witherite BaCO3; assay reported as Ba converts to the declared species using molar-mass ratio only with confirmed speciation, not one interchangeable barium product. Fluorite is CaF2; as-F assay converts to CaF2 using M(CaF2)/(2M(F)) only when that F is confirmed in fluorite; fluoride-ion/other F species are separate. Boron assay as-B2O3 equivalent is not actual oxide: elemental B mass = B2O3-equivalent mass2M(B)/M(B2O3), preserving assay basis and without asserting a borate mineral purity. Natural H3BO3 dry fraction gH <=0.85 requires measured species and geological origin; as-B alone cannot establish H3BO3 if other borates are present. Identify kieserite/epsomite and retained hydration independently; neither crystal-water release nor sulfate assay establishes free water or pure MgSO4. Actual admitted calcination uses independent input/output weighing, phases, free/structural water, carbonate CO2 and dust balances; no unchanged hydrate mass, fixed yield or assumed conversion. Recovery uses matched input/output contained identified species after stock correction, not output grade alone. Reconcile feed solids, accepted grades, actual co-products, waste rock/tails/dust, thermal losses and stocks, plus fresh/recycled/evaporated/discharged water separately. No empirical purity, yield, reagent dose or utility intensity defaults. | |
| validate_coverage | handoff | Verify each applicable exchange, its provider or environmental compartment and final waste fate; identify skipped checks, unresolved identities, missing measurements and upstream gaps. Errors or unassessed mandatory coverage cannot be labelled complete. |
10. Published Dataset Profile

|---|---|
| dataset_role | foreground_dataset |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Supply1 kg accepted net as-received product of one actual natural chemical-mineral family/state/gate, not1 kg pure BaSO4, BaCO3, CaF2, elemental boron/fluorine or B2O3 equivalent |
| excluded_use | Manufactured salts/acids/oxides and HF/elemental fluorine; brine-separated borates; natural boric acid above85% H3BO3 dry weight; formulated mixtures/finished articles; minerals of another specific category; unreviewed residual or thermal identity |
| required_metadata | site/year; actual family and geological origin; mineral phase/formula, raw/prepared/concentrate/calcined gate, residual no-other-category review; free water and structural water method; dry/as-received assay and impurities, BaSO4 versus BaCO3, CaF2 versus F, B versus B2O3 equivalent and natural H3BO3 criterion; actual thermal phase/mass losses; supplier/geography/voltage electricity and fuel/water origin; mine/preparation route and each actual reagent; stocks/co-products/residues/releases/fates; lifetime construction/closure and allocation; packaging/transport. Representative natural-barite Product/Mass UUID unresolved; a baryte elementary resource is not this product. Each other family gate needs its own confirmed natural product identity; current CPC3 HS2022 correspondence and residual family assignment require independent review |
| required_quality_disclosure | Identity and measurement gaps; boundary coverage; uncertainty; allocation; temporal and geographical representativeness |
| update_trigger | Changed product, route, yield, supply, waste fate, site or representative period |
