How Do You Build A Magnetic Sluice?
Build a magnetic sluice to separate out the black iron when prospecting for gold. Save your back by removing the iron at the site and returning it to the same location where you extracted it. Carry the same amount of gold out with you with less effort. A magnetic sluice can separate the gold by trapping it in different ridges as the larger sediment rolls over the top of the ridges. Cut four pieces of plywood using a hand saw. Cut the first piece to be 1 by 4 feet to make the base of the sluice. Cut two side walls 5 inches wide and 4 feet long. Cut the end board to attach a 13 1/2-inch wide by a 5-inch tall board. Make the sluice frame from the plywood. Pre-drill pilot holes for screws to hold the sidewalls to the base at a 90-degree angle. Glue the side walls onto the base using waterproof wood glue. Screw the side walls on with galvanized screws every 5 inches. Do the same thing to attach the 1-foot by 5-inch piece of plywood to the back. Add a bead of the waterproof wood glue in the
