Magnesite
Magnesium-carbonate mineral requested by MgO-equivalent chemistry and impurity profile.
Mining & MineralsIndustrial Minerals
Magnesium Ore
Magnesite and magnesium-bearing mineral feedstock sourced by MgO chemistry and size.
The commercial term magnesium ore can refer to magnesite or other magnesium-bearing mineral feedstock; it does not mean metallic magnesium. Duara Group requires mineral identity, chemistry, processing state and end use before approaching a source.
Bulk supply available upon request. Source and supply available upon request.

Available types and commercial grades
The options below can be investigated against a complete buyer specification. Availability, producer, origin and conformance are confirmed in the written quotation.
Magnesium carbonate-bearing ore
Buyer-defined feedstock where mineralogy and processing suitability are confirmed by analysis.
Sized lump
Crushed and screened material supplied to an agreed lump-size range.
Powder feedstock
Ground product specified by mesh or micron distribution.
Buyer-specified mineral
Other magnesium-bearing material is considered only when mineral identity and use are clear.
Typical specification points
These are enquiry fields, not published lot values. The final specification and test basis must be agreed for each supply.

Magnesium Ore procurement guide
The commercial term magnesium ore can refer to magnesite or other magnesium-bearing mineral feedstock; it does not mean metallic magnesium. Duara Group requires mineral identity, chemistry, processing state and end use before approaching a source. A useful industrial commodity enquiry defines chemistry or grade, physical form and the process in which the material will be used.
Industrial applications
The stated applications are Refractory manufacture, Magnesium-compound production, Construction-material inputs and Industrial mineral processing. End use determines which composition, impurity, size, surface or processing parameters are commercially relevant.
Chemistry, grading and test basis
Set the acceptance schedule around Mineral identity and processing state, MgO or magnesium-carbonate content, SiO2, CaO and Fe2O3, Loss on ignition and moisture and Lump or powder particle size. State sampling point, preparation and analytical method, permitted tolerances and whether independent inspection or an umpire process is required.
Bulk mineral handling
Confirm lump, powder, concentrate, ingot, sheet or other required form as applicable, then define bags, drums, bundles, containers or bulk loading, unit-weight limits, moisture protection, dust controls, unloading equipment and storage conditions.
Information to include in your quotation request
Send the commodity and form, process use, Mineral identity and processing state, MgO or magnesium-carbonate content, SiO2, CaO and Fe2O3, Loss on ignition and moisture and Lump or powder particle size, quantity and shipment size, packaging or bulk loading basis, destination and Incoterm, sampling/inspection terms and required analysis documents.
