Rcovery of gold in pyritic ores - Mine Engineer.Com

Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns. The incidence of fine gold's quantity also appears to be related to the gold concentration, as well. If the assay is 2 ounces per ton, there are generally larger gold particles present along with the .

Recovery of fine floating gold

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.
