Underground hard-rock mining accounts for 40 percent of global mining operations but only 12 percent of run-of-mine (ROM) production. 1 Run of mine is ore that is mined and crushed. In this article underground mining refers to underground hard-rock mining; thus, underground soft-rock mining, such as coal, is excluded.

The sides slope outwards at an angle of about 30° to the bottom, and are about 5 inches wide. A riffle is a useful addition, formed by the thickening or bulging inwards of the side, situated about half-way up the latter and running about half-way round the pan. The method of using this pan embraces several operations.
Sluicing is the use of a "sluice box" in a creek or river to separate gold from gravel. (See our sluice kit below for a quick and easy way to get started with sluicing for gold.) A sluice box is a metal, wood, or plastic channel that …
The pump is used to force water over the material in the hopper and then over riffles of the sluice box. Gold is 19.3 times heavier than water, so the sprayers will help separate the gold from the sand, washing out a lot of the sand while the gold gets caught in the miners moss, or miracle mat, in the sluice box.
