Expert Reviews: The Best Portable Gold Sluice Boxes for …
A sluice box is a device used in gold prospecting to separate gold from dirt and gravel. It consists of a long, narrow box with riffles, or obstacles, along the bottom. Water is directed through the sluice box, and as the material is washed through, heavier materials like gold settle behind the riffles while lighter materials are washed away.

Sluicing for Gold: Best Practices and Setup Guide
The angle of the sluice box should be adjusted to achieve the optimal water velocity, with the general guideline of 1″ drop per foot of box length. However, the angle should be adjusted based on the material being processed to prevent the loss of fine gold and ensure proper breakdown and separation of concentrates.
what is the best sluice box setup for catching fine gold?
With angle, you don't want completely flat on a drop riffle (on a sluice anyway, dredges are different due to the water velocity) because without enough drop to create the vortex in the drop riffles, the sluice can pack up solid and then the gold will just migrate on out. You need some angle/drop to help clear out the drop riffles.
