Sluice design can lead to higher gold recovery if the force of the water traveling through the sluice is decreased. A series of rifles can help break the flow to improve recovery. A zig zag sluice also achieves this by creating a drop between the first and second platform that disrupts the velocity of the water as it travels down the sluice.

May 01, 2013· Highlights 3″ Knelson Concentrator has been configured to operate under dry conditions. Synthetic ore of tungsten and silica was used to mimic a gold ore. The tungsten recovery at 2 psi air fluidisation was greater than 78% (grade of 6%). The tungsten recovery at 3 psi air fluidisation was 69% (tungsten grade 15%). The potential to operate a Knelson .

The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery ...

instantly folded back under the centrifugal force, sending the hot flast over to burn a hole in the couch, the crucible to land on the rug, and most of my ounce of gold in tiny bits all through that rug. Amazingly, I wasn''t hurt. After I realized what I''d done, and replaced that silly piece of brass with some heavy steel angle iron,

The Gold Cube''s forced gravitational, centrifugal and columning effect is called "the GForce." * Vortex matting traps gold and self cleans for hours of use. Vortex Matting. The Gold Cube''s vortex matting works because water flow interacts with a combination of very small pillar walls and cavities—about 7,056 of them per mat.

To overcome these limitations, new apparatus utilizing centrifugal force in fluidization have been recently designed and are used more and more in gold recovery. These apparatus, Knelson and Falcon Superbowl gravity concentrators, provide good recoveries for very fine particles up to 38μm and finer.
