Rcovery of gold in pyritic ores Mine Engineer.Com

2013-1-13 · Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to

rcovery of gold in pyritic ores mine. In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are

Rcovery of gold in pyritic ores. I will say that from my understanding many seem to agree that in sulfide gold ores the occurrence of gold appears to occur as a replacement of other minerals possibly iron. One USBM paper summed up five noticeable characteristics of auriferous pyritic ores.

Flotation kinetics of a pyritic gold ore ScienceDirect

2011-1-17 · Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant

Characterizing the distribution of gold in pyritic

2003-4-1 · Auriferous pyrite is an important ore in the Green’s Creek polymetallic-sulfide deposit. Pyritic ores have textural and crystal forms that range from primitive framboidal spherules to euhedral crystals. The gold associated with the pyrite at Green’s Creek is found in concentrations at the ppmw level and necessitates the use of secondary ion mass spectrometry.

2001-2-1 · Selectivity of gold in pyritic ores Klimpel and Isherwood (1993) studied the efficiency of gold flotation. A comparison test was used with three different collectors, S-701, F-100, Mercapto-benzothiazole (MBT) and a 50/50 combination of MBT and F-100. The recovery of gold with respect to the pH is shown in Figure 1.
