Some years ago, I worked in alluvial gold exploration and became fascinated by the facts and fiction of the old mining districts. However, there didn't seem to be a geological model to provide an understanding of what was required to produce profitable accumulations of alluvial gold.
Before a placer mining operation can begin, the first task is to identify where drainage has deposited gold into sediment layers. To locate a deposit, prospectors use pans to evaluate the surface materials.
Profitable beach mining is actually easier than ever. Modern equipment and quality sluice box matting have helped increase gold recovery rates.
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...
The Different Types of Placer Gold. Placer gold can be divided into several types depending on where it's found. For instance, gold that has just broken loose from the vein and rests in its vicinity is generally referred to as "residual placers", while gold that has made it into a stream is called "alluvial placer".
