» Setting the Proper Water Velocity Through a Sluice Box

Le Trap Sluice. As a general rule, the optimum slopesetting of a sluice is around one inch of drop per linear foot of box. This can change, depending upon the volume and velocity of water being used, and/or the average shape, size, volume or weight (specific gravity) of material that you are processing. There is no exact formula for setting ...

3. Magnetic separation: After washing, the 02mm material flows into the drum magnetic separator to remove the magnetic ore, and then is stored in the slurry pool. 4. Gravity Separation: The 210mm material will flow to the gold sluice box, so the 210mm gold particles can be captured. And the +10mm material will be sent to the waste pile.

Gold Mining Process

Gold Mining Process

The gold mining process is complex and goes beyond what most people imagine — miners in hard hats working underground or operating large, noisy mining equipment are images that often come to mind. However, the actual mining of gold ore is only one step in a complex gold mining process. Before miners can extract gold ore from the ground ...
