Requirement-Led Quality
From a representative sample to a reliable result.
A result only has value when the sampling basis, test method, unit and acceptance limit are understood. Before recommending a grade, we review what the mineral must achieve in the buyer’s process and which parameters are commercially critical.
Testing may be completed through the appropriate production or laboratory facility according to the product and order. The final scope, frequency and reporting basis are confirmed with the buyer.
- Application and specification review
- Product and grade selection
- Sampling and result verification
- Technical and export documentation
Laboratory & Physical Evaluation
Tests selected around the product and its application
The parameters below are typical examples. Applicable tests, methods and acceptance limits are confirmed for the selected grade and order.
Chemical composition
Product chemistry may include CaCO3, CaO, MgO, SiO2, Fe2O3 and other parameters relevant to the selected mineral and application.
Particle-size control
Mesh size, sieve residue, top size or particle-size distribution can be reviewed according to the product form and buyer requirement.
Moisture and loss on drying
Moisture is checked when it affects flow, storage, processing, packing weight or the stability of the customer’s production process.
Whiteness, brightness and colour
Optical properties can be assessed where appearance, opacity or finished-product colour is commercially important.
Bulk density and physical form
Powder, granule and lump products may require checks for density, form, grading, handling behaviour and visible contamination.
Application-specific checks
Additional parameters can be agreed for filtration media, feed minerals, glass raw materials, coatings, polymers and other applications.
From Enquiry to Release
Five controlled steps before shipment
The order moves through a practical sequence that keeps the supplied product, test basis, packing and documentation aligned.
Define the acceptance basis
We confirm the product, application, target values, tolerances, test method and required documents before supply.
Select and prepare samples
Representative samples are collected, identified and prepared to reflect the relevant lot or shipment.
Test and review results
Applicable physical and chemical results are reviewed against the agreed purchasing requirement.
Inspect packing and loading
Bag condition, markings, quantity, loading arrangement and container readiness are checked as applicable.
Release documents and shipment
The commercial and technical records required for the order are coordinated before dispatch.
Final shipment reviewProduct, packing, quantity and records are checked against the approved order basis.
Technical Documentation
Clear records for technical and commercial confidence
Document availability and reported values depend on the product, shipment and agreed customer requirement.
Technical Data Sheet
Typical product properties and available grade information.
Safety Data Sheet
Handling, storage and safety information for the supplied material.
Certificate of Analysis
Reported results for the applicable lot or shipment when agreed.
Inspection Records
Packing, quantity, loading and traceability records as required.
