What are hydraulic riffles?

Hydraulic riffles are a system of riffles that have a built in manifold that injects water into the gold recovery mats, and fluidizes the gravel that is retained in a specially designed deep riffle system for a fluidized bed that greatly enhances fine gold recovery.

What degree should a sluice box be set at?

A sluice box should be set up in a creek or river with a steady flow of water, so that the lighter materials can get flushed out of the sluice box, while the heavier gold and black sands are trapped. As a general rule of thumb, it should slope around 5-7 degrees to function efficiently.

What is the best sluice mat?

Quickly becoming the industry’s #1 mat for SUPER FINE gold, including beach gold, the motherlode mat is a great performer in just about all sluices. Most people use it at the END of their sluice system. Some use it exclusively because they are targeting 100 – 300 mesh flour gold.

What angle do I set my Highbanker?

between 5 – 7 degrees
When setting up a sluice the proper angle must be observed. It’s usually between 5 – 7 degrees of slope and should allow most round rocks and pebbles to pass through easily. You don’t want the material zipping through but rather kind of tumbling through slowly.

What is a Highbanker sluice?

A power sluice, sometimes called a highbanker or hibanker, is a piece of gold prospecting equipment that uses a pump to force water through a sluice box to mimic the natural flow of a river. Sometimes a hopper box with spray bars and a classifier sieve (or grizzly screen) is employed.

How does sluice box work?

Sluice boxes work by essentially creating a straight, consistent channel, with regularly spaced slow spots created by riffles. Each riffle creates an eddy, a backflow of water that allows the gold to settle out. Material is placed at the top of the box and carried in suspension down the channel.
