Oct 16, 2011· The proposed concept of "micron gold" is that it is in metalic form, but so small that it remains in suspension rather than sinking to the bottom, like flour gold does. And it can't be seen with the naked eye. And for whatever reason, it doesn't float on top of the water, like very fine particles of gold will do sometimes.
Jan 24, 2014· The gold does not stay attached to the bubble in the froth of a flotation cell. Flotation as a method of recovering metallic gold is a poor way to go. Flotation works great as way to recover sulfides, including sulfides that have microscopic gold encased in them, but it does not work for recovering fine, free gold.
Indeed, jigs are good down to 53 microns (270 mesh) and lower however recovery does fall away. It is the finer size fractions (<53 microns) that can be more troublesome to recover and spirals, tables, etc. have been used with success. Even flotation, if the gold surfaces are clean, can be useful.
Recovery of fine floating gold. ... In a small recirculating operation you can use a Jet Dry or dish soap to break the surface tension and the gold will not float anymore. With a dredge as long as you don't bring the gold to the surface it shouldn't float. Maybe a deflector to keep it down in the sluice might help.

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.

Apr 14, 2015· Flotation is not a good method for fine gold recovery. Gold is dense and its ability to be floated is only fair. Flotation of gold has been done in laboratories, but it is not a commercially used method because of the difficulties involved, there are many methods of fine gold recovery which are better than flotation.

The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve. A 45 micron particle of gold would dissolve in 10-13 hours, while a 150 micron particle might take from 20 to 44 hours to dissolve in the same solution.
The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores.
