Fine Gold Recovery. Separating Placer Gold Particles
Fortunately there are quite a few good fine gold recovery systems on the market that are both efficient and cost effective. A few hundred dollars will generally get a prospector set up with a system that will do an excellent job of retaining the finest gold in their concentrates. A favorite among prospectors is the Blue Bowl Concentrator. It uses a simple design of circulating water (much like a flushing toilet) to separate any lighter material and black sands while keeping the gold

PLACER GOLD RECOVERY METHODS - Denver Mineral
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 as-sayed gold values, and as late as 1945 recovery of free gold averaged only 70-75% (Spiller, 1983). Moreover, it is likely

Gold Recovery : 8 Steps (with Pictures) - Instructables
The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery ...

2017-10-1 The recovery of gold decreased for fine sizes but it was clearly dependent on the feed gold grade (Laplante et al., 1996). Putz (1994) and Vincent (1997) discussed the rationale of using the LKC (Laboratory Knelson Concentrator) to evaluate the circuit performance, when the ore, equipment or flow sheet limits gold recovery.
