Chalcopyrite dissolution rate law from pH 1 to 3

Geologica Acta, 2009
Chalcopyrite dissolution kinetics in the pH range of 1 to 3 were studied by means of long-term flow-through experiments to obtain a dissolution rate law which can be coupled with reactive transport models to forecast Acid Rock Drainage.
