Antimony ore, concentrate and ingots supply
AHR reviews antimony by material form, Sb assay, moisture, impurities, quantity, packing, destination, inspection and shipment documents. Buyers receive a clearer basis for a quotation-ready request.
Start with the material basis, not the word antimony.
Ore, concentrate and metal are not interchangeable offers. Each form has a different assay basis, impurity profile, packing method, inspection need and commercial model.
AHR can then review whether the request is technically defined, commercially comparable and realistic for the proposed route.
What buyers should define first
- Material form: stibnite-bearing ore, concentrate or antimony metal.
- Target Sb assay, minimum acceptance level and dry or wet reporting basis.
- Maximum arsenic, lead, mercury, sulfur and other buyer-defined limits.
- Trial quantity, recurring volume, shipment window and destination.
- Sampling party, laboratory, controlling certificate and dispute method.
- Packing, palletization, Incoterm, origin evidence and document list.
Choose the form that matches the next industrial step.
AHR reviews the requested form against processing route, quality evidence, packing and destination. Availability and final specification remain lot-specific.
Antimony ore
Use ore inquiries when mineral source, Sb grade, mineralogy, moisture, particle size and beneficiation fit must be reviewed before processing or resale.
- Stibnite-bearing material
- Assay and mineralogy review
- Moisture and penalty elements
- Bulk, bag or FIBC packing
Antimony concentrate
Use concentrate inquiries when dry metric tonnes, Sb assay, moisture, arsenic, lead, sulfur, payability and sampling rules control acceptance.
- Lot-specific assay basis
- Dry and wet weight alignment
- Penalty and deduction logic
- FIBC or agreed bulk handling
Antimony ingots
Use ingot inquiries when purity, grade, dimensions, unit weight, lot traceability, palletization and delivery basis must be confirmed.
- Purity and trace elements
- Heat or lot identification
- Bundle and pallet details
- Review the dedicated ingots page
Compare the same commercial basis before comparing price.
This table defines procurement logic. It does not state guaranteed grades, universal packing or current availability.
| Buyer criterion | Ore | Concentrate | Ingots |
|---|---|---|---|
| Primary decision | Mineral source and beneficiation fit | Smelter feed and payable content | Metal purity and downstream alloy use |
| Main value basis | Sb assay, mineralogy and recoverability | Dry contained Sb and agreed payability | Purity and delivered metal weight |
| Moisture relevance | High | High | Normally not applicable |
| Typical controls | Sb, As, Pb, Hg, sulfur, size, moisture | Sb, moisture, As, Pb, Hg, sulfur, payability | Purity, trace elements, dimensions, lot identity |
| Evidence | Representative sample and assay | Sampling report, assay and moisture certificate | Lot-specific CoA or grade certificate |
| Packing review | Bulk, bags or FIBC | FIBC, liner, pallet and net weight | Bundles, pallets, straps and lot marks |
Use buyer targets and lot results, not invented universal grades.
The final contract should state the test method, reporting basis, acceptance limits, sample identity and controlling certificate for the selected form.

Indicative procurement fields do not confirm a shipment. Final values must come from a lot-linked certificate, agreed sampling method and written commercial offer.
Normalize dry tonnes and contained Sb before comparing concentrate offers.
This calculator handles physical quantity only. It does not calculate final payable value, treatment charges, penalties, freight, tax or inspection cost.
Dry tonnes and contained antimony
Enter the gross shipment weight, moisture percentage and Sb assay. The example starts with 100 tonnes, 8% moisture and 45% Sb.
Contained Sb = dry tonnes x assay / 100
Interpretation: the result is not the settlement amount. A contract may also apply payability, free deductions, treatment charges, impurity penalties, benchmark dates and umpire assay rules.
Application fit depends on form, chemistry and downstream process.
The word antimony does not establish suitability. Buyers should name the intended process and technical standard before asking for a material recommendation.
Lead alloy systems
Selected battery grids and other lead alloys use antimony to adjust hardness and performance. Purity, trace elements and alloy composition must be confirmed.
Flame-retardant routes
Antimony trioxide can be used as a synergist in selected formulations. Buyers should specify oxide requirements rather than assume ore or metal is a direct substitute.
Specialty metallurgy
Antimony can be used in selected alloys and metal systems. The required form, grade and impurity limits depend on the production route.
Compounds and conversion
Processors may convert ore, concentrate or metal into downstream antimony compounds. Feed suitability requires process-specific review.
Connect the sample, laboratory result and shipment lot.
A certificate is useful only when the material identity, sample ID, lot, method, reporting basis and issue date can be traced to the shipment being purchased.
Requirement review
Confirm form, Sb target, impurity limits, quantity, application, destination and documents.
Supplier and origin review
Check the legal counterparty, origin chain, processor, warehouse and proposed route.

Set the controlling assay, allowable variance, penalties, payability and dispute mechanism.
Pre-shipment inspection
Check quantity, packing, labels, condition, container, seal and required certificates.
Document release
Match the final invoice, packing list, origin evidence, transport record and inspection files.
Separate company proof, product proof and shipment proof.
Available documents depend on product form, origin, supplier, shipment stage and contract requirements. A company certificate does not replace lot-specific shipment evidence.
Company and counterparty
Registration, authority, bank details, address, relevant certifications and due-diligence records.
Material evidence
Certificate of Analysis, assay report, Safety Data Sheet, specification, sample ID and lot reference.
Independent controls
Sampling report, laboratory report, weight certificate, condition record and inspection certificate when agreed.

Offer comparison rule
Compare offers only after normalizing material form, dry tonnes, contained Sb, impurity limits, packing, inspection scope, freight basis, destination and quotation date.
Historical or third-party market references are context. They are not a live AHR selling price and do not replace a written shipment quotation.
Expose failure points before payment and loading.
The purpose is not to claim zero risk. It is to define the evidence and controls needed for the actual transaction.
Wet and dry basis mismatch
Contained metal is compared using different weight bases. Define the moisture method and settlement basis.
Generic or unmatched CoA
The report does not identify the shipment lot. Require lot-linked sample and certificate details.
Unclear origin or route
The seller cannot show the source, processor, warehouse or export chain. Review origin and route evidence.
Undefined sampling
The contract does not state who samples, where or how disputes are handled. Agree the procedure before shipment.
Different analytical methods
Results may not be directly comparable. Define the method, laboratory and controlling certificate.
Unpriced logistics scope
Freight, handling, inspection or duty responsibility is omitted. Compare on the same Incoterm and destination basis.

Antimony procurement FAQ.
These answers help buyers prepare the specification, inspection scope and shipment request.
Which antimony forms can AHR review?
AHR can review requests for antimony ore, concentrate and ingots. Buyers should state the required form, application, quantity, destination and documents. Other antimony materials should be described explicitly rather than assumed available.
What Sb assay should a buyer specify?
The target depends on material form and downstream process. State the required minimum or range, dry or wet basis, analytical method and acceptance rule. Do not rely on a generic product name.
How is moisture handled in a concentrate quotation?
Moisture affects dry shipment tonnes and contained Sb. The contract should state the moisture method, sampling point, maximum level and settlement basis.
Which impurities should be reviewed?
Common buyer-defined controls may include arsenic, lead, mercury, sulfur and other process-specific elements. Limits and analytical methods must be agreed for the actual application.
Can third-party sampling and inspection be arranged?
Inspection can be coordinated when required. The contract should define the inspector, location, scope, sampling method, laboratory, controlling certificate and dispute process.
Which documents may be available before shipment?
Depending on the material and stage, buyers may review a CoA, assay, Safety Data Sheet, origin evidence, packing data, inspection records and draft shipment documents. Availability must be confirmed for the actual lot.
How are dry tonnes and contained Sb calculated?
Dry tonnes equal gross tonnes multiplied by one minus the moisture fraction. Contained Sb equals dry tonnes multiplied by the Sb assay fraction. Final payable value may also include payability, deductions, penalties and charges.
Is a market benchmark the final shipment price?
No. A benchmark may refer to a different form, grade, location or date. A shipment quotation must state the material basis, origin, quantity, Incoterm, destination, inspection scope and validity.
What information is required for quotation?
Send the form, Sb target, impurity limits, quantity, schedule, application, packing, destination, Incoterm, inspection needs, document list and company contact details.
Can an umpire laboratory be included?
Yes, when both parties agree. The contract should define retained samples, trigger conditions, laboratory selection, acceptable variance and how the umpire result affects settlement.
