Abstract

See full text

A highbanker may be used with sluice mats to separate heavier metals from placer deposit. The highbanker includes a hopper assembly, a trough assembly, a brace member, and a plurality of legs. The trough assembly includes first and second trough sections. The first trough section includes a first surface and is pivotably connected to the hopper assembly. The second trough section includes a second surface, with the second trough section being removably attachable to the first trough section. The brace member extends between the trough assembly and the hopper assembly. The plurality of legs is removably attachable to the trough assembly. In an assembled configuration, the second trough section is attached to the first trough section so that the first surface and the second surface define a substantially continuous surface for accepting the sluice mats. In a nested configuration, the second trough section is nested within the first trough section.
