Unroasted iron pyrites

1. Scope and Applicability

Supply of natural unroasted iron-pyrites mineral ore, mineral concentrate or powder at one declared mine, preparation/loading or expressly included delivery gate. Include actual surface/underground extraction and ore-only loading, or actual physical recovery from jointly mined mineral feed, freshly generated mineral-beneficiation tailings or independently identified old mineral-tailings stocks. Purchased ore/concentrate and waste-classified old tailings have separate provider/fate and upstream allocation or justified cut-off; they are not interchangeable zero-burden feeds. Actual crushing/screening/sorting, gravity/magnetic separation, grinding/flotation, thickening/filtering, free-water drying, pulverization/sizing and packaging are conditional on product and mineralogy, not mandatory flotation or a recipe copied from a copper-mine case. Retain unroasted iron-disulfide mineral identity with measured Fe/S, pyrite phase, impurity and moisture evidence. Other iron-disulfide mineral variants require independent category/phase confirmation; pyrrhotite, chalcopyrite and arsenopyrite are not automatically this product because they contain iron and sulfur. Natural pyrite recovered from geological mineral tailings may qualify with actual state/grade proof; synthetic iron disulfide, smelter slags, chemically precipitated sulfides, roasted pyrite/cinder, iron oxide concentrates, elemental sulfur, sulfur dioxide and sulfuric acid are different products. Roasting, chemical sulfur extraction, smelting and downstream steel/glass/abrasive-wheel manufacture lie outside the unroasted mineral gate. Include attributable mine development/rehabilitation, tailings, acid-drainage/water and dust controls, actual storage losses and explicitly agreed delivery through the selected gate. epa-pyrite-recovery-1994, wco-hs25-2022, ifc-mining-2007

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_basis	final_product	Mass	kg	D is the positive accepted net gate-output total in kg. Exclude packaging and cancelled internal transfers. cp_output records D; every card uses per 1 kg reference flow.
conversion	utility and material rows	Declared row property	kg; m3; MJ	Retain raw readings. Electricity: 1 kWh = 3.6 MJ. Mass/volume conversion requires measured density, temperature and applicable pressure; retain water content and active chemical fraction.
category_balance	production	Mass	kg	D is independently weighed positive accepted net as-received unroasted mineral kg at selected gate, excluding packaging/rejects. Measure wet-basis free-water fraction w with0 <= w <1; dry mineral mass = D*(1-w). Measured dry-basis sulfur fraction gS with0 <= gS <=1 gives contained S kg = D*(1-w)*gS; keep D denominator. Distinguish total S, sulfide S, sulfate S and measured mineral phases; do not infer pure FeS2 content or recovery from theoretical sulfur/iron stoichiometry. Reconcile dry solids and Fe/S plus relevant impurities across feed, accepted grades, separate copper/other co-products, tails/rejects, dust, stock and actual oxidation/dissolution losses. Recovery uses matched dry feed/output masses and assays with stock corrections, never concentrate grade alone. Purchased sulfuric acid adds sulfur separately from geological sulfide; neutralization residues and measured sulfate transfers/releases retain species versus elemental-S basis. Reconcile new/recycled/evaporated/discharged water separately. Drying/handling must retain declared unroasted phase; oxidized/roasted output requires classification review. Stored stock, heat/moisture and actual sulfide loss are measured, not assumed zero or automatic SO2; downstream roasting/acid yield is outside.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_hierarchy	joint production	Prefer process subdivision or defensible system expansion; otherwise use demonstrated physical causality. Use economic allocation only with consistent period, price, currency and sensitivity when physical causality is unavailable. Retain the unallocated inventory.	ef-allocation-2021
allocation_product	reference and co-products	Subdivide extraction and distinct pyrite-recovery/drying/micronizing circuits where possible. Retain unallocated jointly mined copper/pyrite/other mineral inventory; use demonstrated physical causality or matched payable-grade/price economic allocation and sensitivity. One mixed pyrite concentrate with trace metals is one physical output, not simultaneous contained-metal output masses. Separate current joint tails, purchased mineral product and genuinely waste-classified old tails with documented upstream allocation/cut-off and actual recovery/rehabilitation burdens; neither historical tails nor idle equipment is automatically burden-free. Development/closure attributed once over measured lifetime output. No automatic credit for avoided acid drainage, tailings disposal, elemental sulfur, virgin pyrite or recycled water.
allocation_waste	waste and recycling	Classify each output by physical state and actual fate. A sale does not automatically make a residue a co-product; internal recycling receives no avoided-product credit. Apply treatment burdens once.

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	D is independently weighed positive accepted net as-received unroasted mineral kg at selected gate, excluding packaging/rejects. Measure wet-basis free-water fraction w with0 <= w <1; dry mineral mass = D*(1-w). Measured dry-basis sulfur fraction gS with0 <= gS <=1 gives contained S kg = D*(1-w)*gS; keep D denominator. Distinguish total S, sulfide S, sulfate S and measured mineral phases; do not infer pure FeS2 content or recovery from theoretical sulfur/iron stoichiometry. Reconcile dry solids and Fe/S plus relevant impurities across feed, accepted grades, separate copper/other co-products, tails/rejects, dust, stock and actual oxidation/dissolution losses. Recovery uses matched dry feed/output masses and assays with stock corrections, never concentrate grade alone. Purchased sulfuric acid adds sulfur separately from geological sulfide; neutralization residues and measured sulfate transfers/releases retain species versus elemental-S basis. Reconcile new/recycled/evaporated/discharged water separately. Drying/handling must retain declared unroasted phase; oxidized/roasted output requires classification review. Stored stock, heat/moisture and actual sulfide loss are measured, not assumed zero or automatic SO2; downstream roasting/acid yield is outside.	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

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

Field	Value
dataset_role	foreground_dataset
downstream_use	secondary_dataset; background_dataset
allowed_use	Supply1 kg accepted net as-received unroasted iron-pyrites mineral at one declared grade/gate; contained sulfur and FeS2 phase are qualifiers, not1 kg pure sulfur or synthetic FeS2
excluded_use	Roasted pyrite/cinder, chemically transformed or synthetic sulfides, smelter slags, iron oxides/metal, elemental sulfur, SO2/sulfuric acid; other metal-ore references, pyrrhotite/chalcopyrite/arsenopyrite without pyrite-category confirmation; downstream chemical/steel/glass/abrasive articles and transport-only services
required_metadata	site/year; natural geological/phase identity and unroasted state; integrated mining/joint recovery/supplied-product/old-tailings route; actual mineral preparation/drying and size; dry-basis total versus sulfide sulfur, iron, pyrite-phase and relevant As/Cu/Pb/other impurity assays; free water; grade/acceptance and stocks; source/provider and tailings burden status; separate joint outputs/allocation; water basin, acidity, discharge/waste fate and storage loss; packaging and gate/transport; lifetime development/closure; representative generic unroasted pyrites Product/Mass at a compatible plant gate does not establish purity or a flotation recipe
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
