Quality Assurance
ISO 9001:2015 certified. Zero-compromise quality at every stage.
Our Approach
The Zero-Compromise Standard
In B2B industrial procurement, a variance in raw material behaviour can cause costly downtime or ruined production runs. At Tara Minerals, our Quality Assurance framework is engineered to eliminate variance at every stage.
Our in-house laboratories operate continuously. Equipped with sophisticated analytical instruments, our chemical engineers monitor, document and certify every production run to ensure absolute compliance with international industrial standards.
- 24/7 in-house laboratory — no third-party delays
- Batch-level traceability — full chain from mine to dispatch
- COA with every large shipment — complete transparency
- Technical Data Sheets available for all products
Our Methodology
4-Stage Verification Protocol
Quality is not inspected at the end — it is verified across the entire production lifecycle.
Raw Material Sourcing
Before a single piece of limestone enters our kilns, core samples are drilled from our mines and analysed for natural silica, iron and calcium distribution. Only reserves meeting our strict chemical thresholds are cleared for processing.
In-Process Thermal Checks
During calcination, digital thermal profiling is monitored continuously. This prevents under-burning (which leaves inert cores) and over-burning (which destroys reactivity), ensuring every lump is optimally porous and reactive.
Hourly Chemical Sampling
As materials exit milling or hydration, automated samplers pull composite samples every hour. Our lab tests immediately for available CaO / Ca(OH)2, reactivity indices and acid insolubles to detect any deviation from specification.
Pre-Dispatch Certification
A final random batch sampling occurs prior to bagging and dispatch. A unique Certificate of Analysis (COA) is generated for large shipments, giving B2B partners complete transparency on the exact composition arriving at their facility.
In-House Testing
Advanced Laboratory Capabilities
Our laboratory is equipped to perform the full range of tests demanded by global industrial buyers across steel, water treatment, paper and chemical sectors.
Every batch undergoes rigorous analysis before dispatch, ensuring consistent quality that meets the most demanding international specifications.
Equipped with sophisticated analytical instruments, our chemical engineers monitor, document and certify every production run to ensure absolute compliance with global standards.
Complex Titration
Precise calculation of active CaO and Ca(OH)2 availability in every batch.
Particle Size Analytics
Laser-guided sieve analysis to ensure mesh conformity down to micron level.
Reactivity Profiling
Time/temperature rise tests measuring rapid and sluggish slaking speeds.
Moisture Analysis
Ensuring hydrated materials are thoroughly dried before bulk packaging.
Acid Insolubles Testing
Quantifying silica and other insolubles critical for steelmaking and paper grades.
Whiteness & Brightness
Spectrophotometric measurement for GCC and PCC coating-grade applications.
