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".
The major flaw of the gravity separation method is that very fine gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of assayed gold values, and …
Placer deposits are masses of gravel or other residual or detrital material that contain one or more valuable minerals that have been concentrated by weathering and mechanical processes. The concentrated minerals are, therefore, resistant to weathering and abrasion, and are typically of greater specific gravity, 3.3–22, than the most common minerals, …
