  • Gold Sluice Box Design - Mineral Processing

    2020-6-25  The gold sluice box is an efficient alternative to panning for gold, allowing the prospector to quickly sift through a much greater volume of sediment. Although many affordable varieties are available to purchase, they are even more affordable to build. With a little knowledge, skill and creativity, a prospector can build a custom sluice box from almost any type of solid material available.
