In case you cant get to the Kalgoorlie Mining Expo, let me share Ian’s flyer with you here.
The flyer explains how the Action Mining GOLD WAVE TABLE works:
Separating by specific gravity, the sand forms in riffles directly under the standing wave of water. Even light blond sand forms riffles, not washing away.
Due to the Standing Wave principle, the heaviest particles remain through the low motion area of the Standing Wave. The wave itself moves; the water directly beneath the wave tends to stand still. The further from the top of the wave, the less motion is in the water.
Thus, the heavier the particle the deeper it will ride and the less motion it will see. The "Riffle Pump" attached to the top bar of the Riffle Bar assists in dropping ‘float gold’ to the table surface, enabling a faster production run without fear of losing gold or other metals that normally would be lost on most tables.
In view of the fact that the table top moves back and forth, the micron particles of heavy material (gold, PGMs, scheelite, copper, zinc oxide, etc.) sink to the bottom under the wave. The finer particles (-600 mesh and smaller) drop into a Skin Effect area. That area is directly against the skin of the table top.
The water in this area does not move with the flowing water but rather sits almost still. The motion of the table causes this Skin Effect water to move in the opposite direction of the flow. Thus the fine gold or mineral moves ‘up’ the table and falls into the concentrate trough.
The gold and/or concentrates can then be washed automatically into a concentrate bucket or a security safe, or vacuumed off the table. Ore should be classified according to size for efficient results.
* Gravity separation
* Separates material to 5 microns
* Recover metal values lost by other methods
* Simple operation – Adjustable water flow, adjustable bump, adjustable tilt
* The Micron Mill Wave Table can be fed from an overhead tank, slurry fed by conveyor belts, or by pipe, depending on your setup requirements.
Click here for the Kalgoorlie Mining Expo Flyer (October 28-30, 2008) and see the pictures of the Micron Mill Wave Table set up and in action. The pictures show the wave theory of the table.
