Five years elapsed before the next real gold find, that being at Mount Britton (known as the Nebo Goldfield) approximately 40 miles S.W. of Mackay. It opened in 1881 when several nuggets were found in the alluvial deposits of Nuggety Gully and Oakey Creek. Records show that gold nuggets of up to 69 ounces were found.

Gold Sluicing 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 has …

Fine gold and small nuggets Can be transported many kilometers from source of gold. Can be ancient alluvial gold deposits in ground lifted high above current stream levels. Large nuggets, may be closer to primary gold source. How is this type of gold transported. Moved by water through gullies, streams, creeks and rivers.

This equipment is for the primary concentration of classified alluvial ore and milled hard-rock ore. It is known for its high-volume, zero-loss fine gold recovery. Our machine is adaptable to any mine operations, replacing sluices and jigs. It runs on turbid water, which is perfect for recycle and settling ponds. Two Models:

The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.

Alluvial Mining, Placer Mining & Dredging. Alluvial miners often ignore the fine gold because sluices and jigs can't catch it. Depending on the size and shape of your gold a sluice may begin to lose gold at 40 mesh. Some alluvial mining deposits have 90% of their gold finer than this where enhanced gravity, iCON, is the only solution.

To separate gold particles from a concentrate, concentrate is fed into the centrifuge through a pipe at the top of the machine in a slurry of around 60-75% water and 40-35% solids. The material collects in a vessel in the center of the machine where high speed rotation creates force that moves the material up the sides of the vessel's walls.

the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

No gold was lost, because his largest gold was around .5mm. The iCON method will improve your process by screening your feed to the proper size. This will reduce the volume of feed and increase the percentage of gold that you recover. iCON Gold Recovery uses a 2 step process; classification and concentration.
