What are ground sluices and how do they work?
Ground sluices are devices used in mining and prospecting to separate gold and other valuable minerals from soil, gravel, and other materials. They work by using a flow of water to wash away lighter materials, leaving behind heavier particles such as gold nuggets and flakes. The process involves shoveling material into the sluice, which is typically a long, narrow box with a series of riffles or obstructions along its length. As water flows through the sluice, it carries the lighter materials away, while the heavier particles are trapped behind the riffles.
