ASSEMBLY AND METHOD FOR GRAVITATIONALLY SEPARATING GOLD FROM SMALL PARTICLES

摘要

An assembly and method for gravitationally separating gold from particles, and specifically for separating small components of gold, less than 1 millimeter from small particles. A series of sieves having graduated mesh sizes, and arranged in a sequential, stacked configuration sieves the aggregate of large particles and larger components of gold. The remaining small particles and smaller components of gold fall into a container. A pressurized column of fluid is forced into the container. The fluid has sufficient flow velocity to suspend the lighter small particles, but insufficient flow velocity to support the denser, high specific gravity gold. Gold has a large specific gravity relative to the fluid and particles. Gravity causes the gold to falls into a transparent collection conduit. Manipulation of valves enables gold to redirect to a collection bin. Fluid flow is shut, enabling small particles to be flushed out through gravitational forces and excess fluid momentum.

1. An assembly for separating gold from small particles, the assembly comprising:
a container, the container defined by an open end, a sidewall, and a bottom end, the bottom end comprising an aperture; a series of sieves having graduated mesh sizes, the series of sieves arranged in a sequential, stacked configuration in general alignment with the open end of the container, whereby a sieve having a small mesh is proximal to the open end of the container and a sieve having a large mesh is distal to the open end of the container; a collection conduit, the collection conduit defined by a source end and a container end, the container end configured to join with the aperture of the container; a fluid source, the fluid source configured to enable the flow of a fluid through the collection conduit; a flow regulation valve, the flow regulation valve operational at the fluid source, the flow regulation valve configured to regulate the flow rate of the fluid; a container valve, the container valve operational at the container end of the collection conduit, the container valve configured to regulate the flow of the fluid to the container; an extraction conduit, the extraction conduit defined by a first end and a second end, the first end in communication with the container end of the collection conduit; a collection bin, the collection bin configured to join with the second end of the extraction conduit; an extraction valve, the extraction valve configured to regulate the flow of the fluid through the extraction conduit; a tailings conduit, the tailings conduit in communication with the collection conduit; and a dump valve, the dump valve configured to regulate the flow of the fluid through the tailings drain.
