The gold is coarse and is easily recoverable; gravity recovery captures a lot but you know cyanide captures the rest so we expect very, very good recoveries out of that deposit in particular. At Comet Well and Purdy''s Reward, we first evaluated the system, because it is a very coarse gold system, this is not your average gold deposit.
Various embodiments of methods and systems are provided for mining alluvial gold deposits. The methods can comprise collecting feed from alluvium and washing the feed at high pressure. The feed can be separated into a plurality of separate fractions. At least one fraction is transferred to a metal sensor system using a conveyer, wherein when gold is detected in a piece of the fraction, an air ...

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals.

The character of alluvial gold deposits presents severe difficulties, and sometimes limitations, on the extent to which metallurgical efficiency can be measured. Very little monitoring of metallurgical performance is practised. An indication of performance is often extracted from the comparison of production to the estimate. This is a dubious practice.
its comparatively high gold recovery has made amalgam an integral part of the small scale gold mining operations. In PNG, most of the gold deposits worked by small scale miners are alluvial deposits, in which the gold particles are liberated from the gangue particles. It is customary to use riffled sluiceboxes

The mines are situated in altered and silicified porphyritic microgranite to the south of a stretch of sandy alluvium. Recorded production is of alluvial gold between 1894 and 1896, and of gold from 16 904 tonnes of ore between 1896 and 1900. The recovery of gold declined sharply in 1900, and by 1901 the field was almost deserted.
