摘要
A reactor for recovering metals such as copper, tin and lead from concentrated, acidic aqueous solutions includes a reaction vessel retaining a bed of scrap aluminum in a packed bed above the bottom of the vessel; a plenum below the packed bed of scrap aluminum, and a filter situated within the plenum, including a first perforated pipe enclosing a coaxial second perforated pipe, through which liquid can be filtered and withdrawn for recirculation into the reactor above the packed bed of scrap aluminum. Metal recovery is effected by reduction of metal ions in solution and precipitation onto the scrap aluminum. Multiple reactor systems including equipment required for pH adjustment of the wastewater also may be used.
