How we scored it
Elemental copper metal from mined ore = 1.0, mineral origin per ISO 16128.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Produced by refining and powdering mined copper ore. As an elemental mineral, it is natural origin regardless of processing.
In plain English
