Sluice plate with spiral pockets

摘要

A sluice plate for capturing and concentrating heavy metal particles has a main plate and a plurality of spiral pockets. The main plate includes a main body and a drafting surface over which a processing mixture flows. The plurality of spiral pockets traverses into the main body through the drafting surface, wherein the plurality of spiral pockets collects heavy metal particles from the processing mixture. Each of the plurality of spiral pockets has a lateral wall that tapers from an upper opening to a lower face. An inner lip is perimetrically and helically positioned along the lateral wall. The inner lip and the tapered nature of each of the plurality of spiral pockets facilitates the movement of the processing mixture within the plurality of spiral pockets, along with the stratification of the heavy metal particles.
