The aim of this study was to determine the combined effect of galvanic interaction and silicate addition on the dissolution of pyrite, the major contributor to acid and metalliferous drainage (AMD).

Porous silicon (PS) films up to ∼150 μm thick with specific surface area similar to 700 m2/g and pore diameters similar to 3 nm are fabricated using a galvanic corrosion etching mechanism that does ...
