Method and apparatus for hydroattrition scrubber

摘要

A method and apparatus are disclosed for separating target particles from surrounding materials such as separating gold particles from the clays in placer deposits. The enveloping material is converted to a slurry, then pumped into a collision chamber through pairs of opposing nozzles. Sets of slurry collide, dislodging target particles from surrounding material. The outgoing slurry is then further processed to separate the particles dislodged by the collision.
