#4720 Whirlpool in a Vat to Separate Gold from Tailings
#4720 Whirlpool in a Vat to Separate Gold from Tailings #4720 Describe a vat that spins up a base of gold tailings into a whirlpool, material being lifted up in the swirl, then lets the material settle out, possibly aided by particular flow mechanics. This is not a centrifuge. Hydrodynamic Vortex Elutriation Vat This apparatus utilizes controlled swirling vortex flow, fluid shear, and gravity-driven hindered settling rather than mechanical centrifugal g-forces (such as those in a Knelson or Falcon concentrator). It operates by converting tangential fluid momentum into a vertical toroidal vortex that stratifies gold tailings by specific gravity and particle diameter. Physical Architecture Vat Geometry: A vertical, flat-bottomed or steep-conical cylindrical vessel (typically with an aspect ratio of 1:1 to 1.5:1 height-to-diameter). The lower section transitions into a conical concentrate sump with an underflow valve, while the top perimeter features a continuous peripheral weir for...
