2. Mining methods of the Klondike Gold Rush - Wikipedia

   en.wikipedia.org/wiki/Mining_methods_of_the...

   Panning for gold was the simplest method of recovering gold, but mostly used for prospecting since it was slow. A faster way was by a rocker box or by sluicing. Dirt was filled into the box or sluice together with water and rocking movements or gravity would make the gold particle go to the bottom whereas sand and fine gold particles would flow ...

3. Rocker box - Wikipedia

   en.wikipedia.org/wiki/Rocker_box

   Like a sluice box, the rocker box has riffles and a carpet in it to trap gold. It was designed to be used in areas with less water than a sluice box. The mineral processing involves pouring water out of a small cup and then rocking the small sluice box like a cradle, thus the name rocker box or cradle.

4. Gold rush - Wikipedia

   en.wikipedia.org/wiki/Gold_rush

   Once it is clear that the volume of gold-bearing sediment is larger than a few cubic metres, the placer miners will build rockers or sluice boxes, with which a small group can wash gold from the sediment many times faster than using gold pans. Winning the gold in this manner requires almost no capital investment, only a simple pan or equipment ...

5. Placer mining - Wikipedia

   en.wikipedia.org/wiki/Placer_mining

   A long sluice box runs along the mine. [16] The sluice box was used extensively during the California gold rush for larger scale operations. When streams became increasingly depleted, the grizzly and undercurrent variants of the sluice box were developed. The grizzly is a set of parallel bars placed at a 45-degree angle over the main sluice box ...

6. Sluice - Wikipedia

   en.wikipedia.org/wiki/Sluice

   A sluice gate. A sluice (/ s l u s / SLOOS) is a water channel containing a sluice gate, a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a river sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a ...

7. Gold mining - Wikipedia

   A rocker box uses less water than a sluice box and is well suited for areas where water is limited. A rocking motion provides the water movement needed for the gravity separation of gold in placer material. [46] Rocker boxes gained popularity during the California Gold Rush in the 19th century and remain in use today.
