What is Placer Gold and How do You Find it

Sep 12, 2018· Placer gold is a term that refers to gold found in a secondary deposit. Usually gold occurs in lode deposits. However, the weathering of the hard rock and action of rivers and even glaciers in some places have carried the fine gold nuggets and particles and deposited them somewhere else away from the original lode deposit.

Gold Sluice Boxes for Prospecting Water Powered Gold

Sluicing is a method of separating and recovering gold from the placer gravel by the use of running water. Gold is caught or trapped by riffles. 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

Dealing with Black Sands: getting all the gold out of your

However, these gravity-based methods are not just specific to gold they capture all the heavy materials in the placer and concentrate them, including black sands. The frustrating thing about black sand is that while it is relatively easy to separate the normal sand and gravel from the gold, it much more difficult to separate the small sized
