Sometimes all that is available is nothing more than a few small flakes. The truth is, new prospectors are sprouting up all across the planet—especially in the developing nations.
The Subsurface Suction Dredge
The problems of the submersible dredge tube are addressed by the subsurface dredge, where the enclosed sluice recovery tube is suspended from a flotation assembly...
