dry-washing for gold goes back to the earliest days of gold discovery, where water was not available to separate the valuable minerals from waste sand and rock. the early miners devised crude methods of utilizing the flow of air and vibration to concentrate and separate valuable materials like gold and gemstones from sand and gravel.
goldlands' technicians have designed and manufactured proprietory industrial gold mining equipment since 1977. the mining machinery manufactured include a host of gold recovery and mineral processors including gold concentrators and separators, portable placer or alluvial wash plants, portable crushers, trommels and scrubbers, gold centrifuges, jig recovery units, rotary helix concentrating

artisanal and small-scale gold mining without mercury. in many countries, elemental mercury is used in artisanal and small-scale gold mining. mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. this process can be very dangerous and lead to significant

highly efficient wet sizing and maximum removal of fines is accomplished by repulping and rescreening the material as it moves down the length of the vibrating screen. the spray water is directed at the wash trough and not the screen surface as spray water directed at the screen surface would result in accelerated wear and could also force oversize particles through the openings.

miner – a person who works in a mine. mine – to dig in the earth for the purpose of extracting ores or other valuable minerals. mother lode – a belt of very rich gold-bearing quartz veins. nugget – an random shaped piece of gold of medium to large size. ore – a mineral-bearing rock, which may be rich enough to be mined at a profit.
riffles are purposeful obstructions which slow the movement of gold in the sluice so it can be trapped in miner's moss, carpeting, or rubber matting in the bottom of the sluice. nineteenth century gold miners used wooden sluices that were at least 12 feet long, but modern gold prospectors primarily use sluice boxes made of plastic or metal which are typically 24, 36 or 48 inches long and 6 to
