An increase in gold and copper recovery was found in the <20 μm fraction to a high level of statistical significance. For the >20 and <38 μm size range, the copper recovery increased to a high level of significance, whereas the increase in gold recovery in this fraction was to a lower statistical significance.
The recovery of fine gold has always been a huge challenge for prospectors. The smaller a piece of gold is the harder it is to recover. Plus, how small does gold have to be before you realize that it just isn't worth the effort to recover. As a result, many gold prospectors have avoided the idea of beach mining.
Most sluice boxes use riffles or obstructions blocking free flow of gravel and sand from being washed out of the sluice box. These restrictions form low pressure pockets behind which gold will accumulate. Gold is 19 times heavier than water and approximately 16.5 times heavier than quartz, so...

Oat gold, fine gold, micron gold (micros), and gold dust are all terms used for the smallest forms of gold. These minute particles get lodged under rocks and pebbles and collect on the top of bedrock. They originate from lode gold upstream that breaks apart and is washed downhill. The farther the gold tumbles, the smaller the fragments get.
HIGmill grind size was 12.5μm, with a gold recovery rate of 82.6%. This increased grind size is attributed to several factors including highly variable mineralogy of the feed ore, increase in ore hardness and high talc concentrations. Overall gold recovery has increased by approximately 6% as a result of the installation of

Extremely fine particles of gold like this can be …
First, the material is screened to remove large rocks and boulders. Then a sluice or jig is used to recover the gold. For deposits with high clay content, the rocks are cleaned with a trommel or rotary scrubber to remove contaminants, and then gold recovery can take place. If a significant portion of the gold is fine (<300 μm), a high G ...
