Flame-Retardant Compounds
Processed antimony compounds, especially antimony trioxide, are used in selected flame-retardant formulations.
Mineral: Stibnite (Sb₂S₃)
Antimony Ore Stibnite for Industrial Processing
Amal Trade coordinates Antimony Ore and stibnite inquiries for qualified smelters, refiners, metallurgical processors, laboratories, alloy producers, and industrial buyers. Commercial supply is reviewed according to representative sampling, Sb assay, mineralogy, moisture, particle size, impurity limits, packing, inspection, and destination requirements.
Stibnite is the predominant ore mineral of antimony. Any binding Sb concentration or shipment grade must be confirmed through the relevant sample or batch assay and written commercial specification.

Product Overview
Natural Stibnite and Antimony-Bearing Ore
Stibnite is an antimony sulfide mineral with the chemical formula Sb₂S₃ and is recognised as the predominant commercial ore mineral of antimony. It commonly has a lead-gray to silver-gray metallic appearance.
Antimony recovered through suitable mineral processing and metallurgical operations is used in processed compounds and alloys. Important downstream uses include flame-retardant formulations, lead-based storage-battery alloys, solders, specialty alloys, ceramics, glass, plastics, and other industrial applications.
The ore itself should be evaluated by mineralogy, total Sb assay, moisture, particle size, associated sulfides, gangue, impurities, recoverability, treatment requirements, and destination compliance.

Downstream Industrial Markets
Antimony Applications After Suitable Processing
End-use suitability depends on ore grade, processing route, refining, product purity, regulation, and customer specifications.
Battery & Lead Alloys
Antimony can be used as a hardening and performance-enhancing alloying element in selected lead-based applications.
Specialty Alloys & Solders
Refined antimony is used in selected solders, bearing metals, specialty alloys, and other metallurgical products.
Glass, Ceramics & Chemicals
Suitable processed antimony products may be used in glass, ceramics, plastics, pigments, and chemical applications.
Sampling, Packing & Export
Information for International Buyers
Final options depend on the material, quantity, physical form, safety review, origin, destination, and commercial agreement.
Sampling & Assay Requirements
- Define the lot or stockpile represented by the sample
- Agree incremental, composite, crushing, and splitting procedures
- Seal samples and maintain a documented chain of custody
- Confirm laboratory, method, detection limits, and reporting units
- Keep retained or umpire samples for dispute resolution
- Link every assay report to the relevant sample or shipment batch
Packing & Export Documents
- Lined jumbo bags, industrial sacks, drums, pallets, or approved packing
- Commercial invoice and packing list where applicable
- Certificate of origin and transport documents
- Certificate of analysis and weight certificate
- Independent inspection report where commercially agreed
- Safety, handling, customs, and destination-required documents
Important safety and compliance notice:
Antimony ore and processing dust require professional occupational,
environmental, storage, transport, and handling assessment. Appropriate
dust controls, protective measures, waste controls, transport classification,
and destination-market requirements should be confirmed before sampling,
crushing, loading, processing, or use.
Commercial Buyer Questions
Antimony Ore Frequently Asked Questions
Clear guidance for smelters, refiners, laboratories, processors, importers, and qualified industrial buyers.
What is Antimony Ore?
Antimony Ore is mineral material containing antimony-bearing minerals. Stibnite, with the formula Sb2S3, is the predominant commercial ore mineral of antimony.
Is every Antimony Ore shipment pure stibnite?
No. Mineral identity, gangue, associated sulfides, antimony grade, moisture, particle size, and impurities can vary by source, stockpile, sample, and shipment batch. Mineralogy and assay should be confirmed before trade.
Which parameters should an industrial buyer request?
Buyers commonly request total Sb, mineralogy, moisture, particle size, arsenic, lead, mercury, sulfur, iron, silica, and other processing- or destination-specific limits.
Can a sample and laboratory report be arranged?
Samples and reports may be discussed for serious commercial inquiries, subject to availability, sample size, preparation, sealing, courier restrictions, testing cost, and agreement on which lot or stockpile the sample represents.
How should representative sampling be agreed?
The parties should agree sampling location, number of increments, composite preparation, crushing and splitting method, sealing, chain of custody, laboratory, test method, retained samples, and dispute procedure.
Which packing options may be available?
Depending on particle size, quantity, loading facility, handling classification, and contract, options may include lined jumbo bags, industrial sacks, drums for samples, pallets, containers, or buyer-approved packing.
Which export documents can be requested?
Documents may include a commercial invoice, packing list, certificate of origin, certificate of analysis, weight certificate, inspection report, bill of lading, safety or handling information, and destination-required records.
What safety considerations apply to Antimony Ore?
Ore and dust should be assessed by qualified occupational, environmental, and transport professionals. Dust control, suitable protective measures, storage, handling, processing, waste management, transport classification, and destination compliance should be confirmed before use.
