95.5-100% Au extraction
ICP-OES checks of final liquid solutions showed nearly complete Au removal from solution by the resin across the tested standard range.
Validation evidence and pilot projects
Validation & Projects
For suitable SORBIONEX Au and SORBIONEX REE projects, we can run an initial test batch on customer material at our cost, with selected verification by ICP-OES or AAS depending on the element and matrix.
Customer material
Test before you commit
Run SORBIONEX on real project material first, then decide the next step from verified data.
Completed Au validation
University of Girona confirmed the SORBIONEX Au loaded-resin measurement principle.
Gold-loaded SORBIONEX Au standards were tested by micro-XRF, EDXRF and ICP-OES. The results showed gold capture on resin, detectable Au XRF peaks and a concentration-dependent EDXRF response.
EDXRF calibration response
Au La net peak increased from 0 to 806.93 Cps between STD0 and STD7, supporting quantitative calibration development.
Micro-XRF confirmation
Gold was detected on individual resin grains, including a clear STD7 spectrum and detectable Au signal in STD1.
Project sample validation
Agnico Eagle Sweden samples showed useful SORBIONEX Au trend response and the next resin-capacity target.
The 53-sample comparison is kept separate from the Girona standard validation. It shows practical ore-sample behaviour: useful trend response across many samples and under-response at the highest laboratory Au peaks because the early V2.1 resin had insufficient loading capacity.
What it proves
SORBIONEX Au can provide practical sample ranking and local feedback when calibrated against reference data for a specific material.
What it does not claim
The early Agnico test should not be presented as final high-grade performance. The correct next step is repeat validation with higher-capacity resin and defined ore-specific calibration.
SORBIONEX REE
REE validation remains a planned university and reference-laboratory programme.
The proposed SORBIONEX REE programme includes University of Girona micro-XRF/EDXRF studies of REE-loaded resin targets and ICP-OES/MS reference verification. The work will address spectral overlaps, calibration, reproducibility, detection limits and matrix-specific constraints.
Public distinction: Girona has completed useful Au loaded-resin validation. REE should remain described as planned verification until approved REE results are available.
Initial test batch at our cost
Start with a limited batch of pulp rejects, prepared samples or representative residue material selected to cover the grade and matrix range for SORBIONEX Au or SORBIONEX REE.
ICP-OES or AAS check
Selected test results can be verified by ICP-OES or AAS, depending on the target element, matrix and agreed scope, so the first decision is based on measured customer-material data.
