| Description | Mass fraction of Cu, Fe, As, Bi and Ag in copper concentrate and Cu, Fe, Pb, As and Bi in copper ore |
| Time of measurements | 2022 - 2023 |
| Status | Measurements in progress |
| Measurand | Mass fraction of copper, iron, arsenic, bismuth and silver in copper concentrate Mass fraction of copper, iron, arsenic and lead in copper ore For Copper concentrate : w (Cu) : (150 - 300) mg/g w (Fe) : (250 - 350) mg/g w (As) : (0.5 - 2.5) mg/g w (Bi) : (50 - 100) mg/kg w (Ag) : (50 - 200) mg/kg For copper ore: w (Cu) : (10 - 30) mg/g w (Fe) : (10 - 30) mg/g w (As) : (100 - 1 500) mg/kg w (Pb) : (50 - 200) mg/kg |

| RMO Internal Identifier | SIM.QM-S13 |
| Comments | The comparison consists, on demonstrate the measurement capabilities in the measurements of mass fraction of Cu, Fe, As, Bi and Ag in copper concentrate and Cu, Fe, Pb, As and Bi in copper ore. Therefore, it is focused on measurement capabilities of category 13, which include the measurement of transition metals, metalloids, and post-metalloids, in two high-silicon matrices, which have a different level of content of the measurands. The comparison is coordinated by Centro Nacional de Metrologia from Mexico in collaboration with Instituto Nacional de Metrologia Qualidade e Tecnologia from Brazil |
