Sluice box

A sluice box is a simple, elongated device used in mining, particularly for gold, to separate valuable materials from dirt and gravel. Water flows through the box, which has a series of riffles or barriers inside. As the lighter dirt and rocks are washed away, heavier materials like gold settle at the bottom due to their weight. Miners can then collect these concentrated materials from the sluice box. Sluice boxes are effective and efficient tools that have been used for centuries in prospecting, making them an essential part of small-scale mining operations.
