ABSTRACT:
Portable sluice equipment is provided for miners backpacking into back country to separate out valuable metals from placer deposits. All major components are made from commercially available PVC plastic conduits and fittings. The principal component is a sluice trough manufactured by first longitudinally cutting a plastic pipe in half, and then cutting spaced transverse back angled radial flow channel grooves throughout the sluice trough to initially receive the concentration of heavy metals. Also longitudinal grooves are cut throughout the length of the sluice trough near the respective top edges. Then when periodically, the main flow of sluicing water is stopped, the sluice trough is rotated about its longitudinal axis, and a minimal flow of water is directed transversely to flush the heavy metals from the transverse back angled radial flow channel grooves into the longitudinal groove. Thereafter, the heavy metal is directed downwardly, via the minimal flow of water, in the longitudinal groove and deposited in a transport container. The sluice trough entry end may be fitted with a ninety degree plastic elbow, in turn supporting a plastic catch basin. A stream water entry may be provided in this elbow to receive stream water, which enters longitudinally above the bottom of the sluice trough to impact the dropping placer deposit material. Also adjustable height spaced bias leg supports are provided, with one being located on each side of the sluice trough, to provide, in combination with a discharge end of the sluice trough, a three point support.
