How Do You Build A Gold Dredge Sluice Box?
Gold sluice boxes are an effective tool for processing gold-bearing gravels. They operate on the basic principle that gold is heavier than other materials. A sluice box creates an artificial channel for water to flow through with a series of riffles running across the flow of water on the bottom of the box. Lighter materials will float in the water and wash through the sluice box, while heavier materials–such as gold–will fall to the bottom and become trapped on the riffles. While a sluice box can be built with a variety of materials, the easiest to work with is wood. Cut one piece of plywood 1 foot wide and 4 feet long. This piece will be the base of the sluice box. Cut two pieces of plywood 4 feet long and 8 inches wide each. These two pieces will form the sides of the sluice box. Cut eight 1-foot-long sections of 1-inch square wooden dowel. These pieces will be used for the riffles and supports. Attach the first riffle at one end of the base board with two screws. Make sure each e
