Types of Gold Mining

This is a list of the different gold mining techniques, from panning, sluice box, rocker box, gold dredging and underground extraction.


Gold Panning

Gold Panning is a mining technique where gold is manually separated from rock and dirt. Gold is more dense than other rock or materials so the gold settles at the bottom of the wide shallow pan. This method is one of the cheapest ways to get started and easiest, but isn't used commercially for large deposits. Gold panning is mostly used at a water source like a river to use the water to wash away the dirt and rock in the pan.

Sluice Box

A Sluice Box, or sluicing is used for small scale mining. Sluicing is used mostly for placer mines, which is a type of mining of extracting gold from alluvial deposits in the ground. A sluice box is a slide with riffles where the gold is collected when water washes the material down the slide. Since gold is more dense, the gold collects in the riffles and miners moss that is on the bottom of the slide of the sluice box.

Rocker Box

A Rocker Box is much like a Sluice Box but it can be used with much less water. A rocker box has holes at the top to stop most of the larger dirt from entering. Once the material goes in the box, the prospector rocks the box back and forth to move the materail through an apron that can collect gold and down riffles and miners moss to collect the gold. This method is used in places where water is limited.

Gold Dredging

Gold Dredging is used by small operations using a suction dredge underwater. A pontoon boat holds a gasoline engine usually that a long tube is connected to a pump and attached to a long vacumn pipe. A scuba diver goes to the floor of a river, lake or ocean and use the dredging suction to extract materials from the ground to the move it up to the pontoon boat on the surface. The material then goes through a sluice box on the pontoon and exits the water and the leftover material back into the water.

Hard Rock Mining

Hard Rock mining is extracting Gold encased in rock. Most of the gold accumalated in the world is done through hard rock mining. Open pit mining or underground mining are the two ways of doing hard rock mining.
