Washing Gravel – The Secrets of Good Gold Recovery
The force of the water separates the gold from the lighter gravels and allows them to get captured into the riffles. In many places, simply shoveling dirt into the sluice is all that is needed. You will get good recovery rates without any extra effort, which allows you to process even more gravel during a day of mining.
