2000-2-29  A novel liquid–liquid separation for the recovery of free or liberated gold from mixtures of fine particles was evaluated. The separation, conducted at 295 K and carbon dioxide vapor pressure of 6.0 MPa, was based on the difference in wettability of precious metals and minerals.Contact angle results indicated that in the presence of water and liquid CO 2, gold was slightly hydrophobic.

Recovery of fine gold particles using a Falcon ‘B’ separator

2009-10-21  Figure 11 – Solids Recovery From A 5kg Feed Mass The gold recovery by size results are shown in Figure 12 and demonstrate that the coarse free gold particles in the coarse feed are readily recovered. For the fine feed sample the gold recovery decreases with increasing particle size. As this stream is a cyclone overflow, it is likely that coarser particles contain only very small amounts of gold and their density is very little different from the gangue. Recovery of minus 20 micron gold-bearing particles was essentially the same for fine

Gold Recovery 101 - Sepro Systems

2019-10-1  While gold is naturally hydrophobic and thus amenable to flotation in the particle size range of 75-300 µm, very fine or very coarse gold does not respond well. Along with the benefits of lower CAPEX and reagent consumption mentioned previously, this can make the addition of a gravity circuit even more critical as it will prevent overgrinding of gold and capture any coarse particles before they report to the flotation

Moreover, it is likely that most remaining placer deposits have a higher percentage of fine gold than placers worked during the gold rush. It is understandable, then, that today more care is given to the re-covery of fine gold.
