Methodologies and protocols
Sampling will include bulk unprocessed materials and waste fractions and processed waste fractions and mine tailings. Unprocessed waste products will be subjected to sorting and dismantling analysis whilst the processed fractions will be sampled and analysed for CRM content. Sampling and analysis will be limited to “particularly interesting” samples with distinctly different matrices.
Sampling, sampling preparation and chemical procedures will be assessed for accuracy, precision, detection limit, comparability, completeness, precision and representativeness to develop and validate methodologies and protocols to update data in future.
