GOLD PLACER DEPOSITS
Clay or cemented gravel seldom can be broken up sufficiently by hand to free all the gold without the use of some form of pulverizer. In a dry washer all gold included in a lump of waste passes out of the machine. As water usually will break up all the gravel and separate the gold from the other material, a better saving usually can be effected

01.12.2020The process eliminates the remaining impurities (if any) from the gold. The raw gold experiences a melting process and treatment with chloride. As a result, any impurities remaining with gold convert into chloride, which automatically gets removed from the gold. The result would be 99.5% to 99.99 pure gold.

Drift Mining
Many miners died in these early drift mining operations. As with an underground operation, the gold-bearing ores needed to be brought to the surface for processing. Ancient gravels would be cemented and generally required crushing before they could be run through a sluice system.
