This involves water that is used to extract gold in a small-scale mine and in prospecting. A sluice box is created for water to pass through. Small obstacles in the box makes gold elements fall out of the flow while the less dense material continues to flow out of the box. Dredging: Only a small part of gold mining is carried out this way today.
