Ores
Selected iron ore, bauxite, chrome ore and copper-bearing materials, subject to specification and lawful sourcing.
Global industry guide
Mining & Minerals
Mineral and ore enquiries are shaped by end-use requirements, assay, moisture, sizing, impurities, loading capability and destination handling.
Industrial minerals
Limestone, dolomite, gypsum, gabbro and related inputs for construction and industry.
Evidence and acceptance
Representative sampling, inspection and clearly defined acceptance criteria reduce avoidable quality disputes.
Producing countries & mineral regions
Mining leadership is commodity-specific. Australia and Brazil are important iron-ore origins; Australia and Guinea are central to bauxite; South Africa and Kazakhstan are significant in chrome; and Chile and Peru are major copper-producing jurisdictions. Current data should be checked by commodity and year.
- Ore grade, geology and beneficiation route differ by mine and deposit
- Mine-to-port rail and road capacity can be as important as nominal production
- Export permits, royalties and local regulation are origin-specific
- Responsible sourcing requires legal origin, ownership and counterparty verification
Common specifications
Minerals are defined by representative assay, physical sizing, moisture and the penalty elements relevant to processing.
- Iron ore: Fe, silica, alumina, phosphorus, sulphur, moisture and sizing
- Bauxite: available alumina, reactive silica, total silica and moisture
- Chrome ore: Cr₂O₃, Cr:Fe ratio, silica, phosphorus, moisture and size
- Industrial minerals: purity, major oxides, loss on ignition, colour and particle size
Uses & processing
Iron ore feeds steelmaking; bauxite feeds alumina refining; chrome ore supports ferrochrome and stainless steel; copper ores feed concentration, smelting and refining; limestone, gypsum and dolomite serve cement, metallurgy, construction and industrial processing.
Mines, beneficiation plants & stockyards
The ecosystem includes mines, crushers, screens, washing or beneficiation plants, concentrators, assay laboratories, rail or truck loading points, blending yards and export stockpiles. Representative sampling must reflect the contractual lot and moisture condition.
Ports & export infrastructure
Major mineral corridors connect dedicated mine railways and bulk terminals in Western Australia, Brazil, Southern Africa and other producing regions to Asian, European and Middle Eastern processing centres. Draught, stockyard segregation and loading rate influence feasible shipment size.
Shipping & handling
Ores and minerals commonly move in dry-bulk vessels. Cargo declaration, moisture testing, transportable moisture limit where applicable, trimming, hold preparation, weight distribution and safe loading and discharge must follow the relevant cargo schedule and vessel requirements.

Mining & minerals FAQ
Practical answers to common early-stage questions.
Why is a recent assay required?
Mineral composition can vary by deposit, bench, stockpile and shipment. A representative, recent assay helps test suitability and define acceptance limits.
What is the main shipping risk for some fine bulk cargoes?
Excess moisture can create instability or liquefaction risk for cargoes classified accordingly. The applicable IMSBC requirements and verified test results must be followed.
Can one specification cover every end use?
No. Smelters, refineries, cement plants, foundries and construction users may require different chemistry, sizing and penalty limits.
Authoritative reference sources
Current production, reserves and cargo-safety requirements should be checked against primary official publications.
