Gold has been treasured since ancient times for its beauty and permanence. Most of the gold that is fabricated today goes into the manufacture of jewelry. However, because of its superior electrical conductivity and resistance to corrosion and other desirable combinations of physical and chemical properties, gold also emerged in the late 20th century as an essential industrial metal.

Flour Gold Recovery

Fine gold is often called "Flour Gold" and is very fine gold that looks like "baking flour". For most it's in the 100 – 200 mesh range. Most "fine gold" that prospectors deal with is in the 50 – 100 mesh range. There is a pretty common rule I use about fine gold. The bigger the water… the more fine gold you'll

May 05, 2010· Most know the heavy visible gold (SpG. 15/19) will sink and where it's normally found in a river. In your case, the 25/1 micron gold (the unaided eye can see down to about 40 micron) can't overcome the surrounding surface tension of the water and is often carried in the middle third of the river's water level.

Figuring out mesh sizes is simple. All you do is count the number of openings in a one US inch of screen. The number of openings is the mesh size. So a 4-mesh screen means there are four little squares across one linear inch of screen. A 100-mesh screen has 100 openings, and so on.

These were effective in the particle size range of 1.5 mm down to 70 microns, yielding efficiencies of 98% for gold in the range of 1.5 mm to 500 microns (35 mesh). The efficiency dropped off dramatically as the particle size decreased, yielding only 65% recovery for -75 micron gold. Illustration of small mercury amalgamator
