An alternative but highly prospective method for the selective recovery of metal ions is based on solid-state extraction, i.e., adsorption of metal ions on a sorbent material from the battery leaching solution without precipitation. The sorbent acts as a metal ion capturing agent that can reversibly bind the metal ions to its surface.

In this method, the barren overburden is removed, often by draglines or shovels, and high-pressure water jets are used to break up and dislodge the tin-bearing sand. A submerged gravel pump then sucks up the slurry of mud and water and raises it to a series of sluice boxes, or palongs, which slope downward and have baffles placed at intervals along their length.
