    This sluice box can be produced in any size and a 60 15 cm sluice costs US$ 75 in USA. The main advantage of this sluice is the high concentration ratio. Gold becomes trapped in a magnetite layer which can be scraped off and washed into a pan. Using a magnet, the magnetite can then be removed and a high grade of gold concentrate is obtained.

    The concentration of free gold in a gold placer is very small and a high concentration ratio is required to make an economic concentrate. There is a great deal more tin in a tin placer than gold in a gold placer. To be economic the ratio of enrichment for tin placers need only be 10 or 20 times.
