Tests are performed in accordance with the scope of accreditation under GOST ISO/IEC 17025-2019, regulatory documents and approved measurement procedures. The full list of accredited tests is given in the Scope of accreditation document in the next section.

Mineralogical studies

From the form of uranium to the mining regime

Uranium-bearing minerals are identified on an X-ray diffractometer. This makes it possible to forecast recovery in advance, calculate reagent consumption and adjust the in-situ leaching regime to the specific part of the deposit.

Pitchblende: Leaching is more efficient: standard regime and lower reagent consumption.
Coffinite: Recovery is more difficult: a stronger regime is needed, including more concentrated sulphuric acid solutions.

What analytical support provides

Speed: Reliable analytical data within the required time
Grade control: Radioactive elements, quality of ores and process solutions
Process control: Tracking changes in process parameters
Lower risk: Early detection of potential process complications
Production planning: Forecasting ore behaviour and more accurate plans
Informed decisions: Operational decisions based on verified data
