Exploring sulfate and metals removal from Andean acid mine drainage using CaCO3-rich residues from agri-food industries and witherite (BaCO3)

Dispersed alkaline substrate (DAS) is a matured passive remediation technology that has shown very high performances treating acid mine drainages (AMD). However, this remediation approach needs to improve its environmental footprint as well as to ensure almost complete water sulfate removals for lon...

However, this remediation approach needs to improve its environmental footprint as well as to ensure almost complete water sulfate removals for longs periods of time. The present study improves the use of witherite (BaCO3) as a reagent on DAS-type treatments to induce highwater sulfate removals in the context of Andean AMD.

Two sets of column experiments were developed with various flow rates (1.5–5.4 L/day), net acidities (202 and 404 mg/L as CaCO3 eq.) and reactive agents (calcite, eggshells, seashells and witherite).
