12/01/2022· Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of
29/02/2016· In simple ores, the amenability of the composite to the recovery influenced by the gold minerals distribution, gold particle size, degree of oxidation and occurrence. Sometimes, gold deposits are not exploited due to the mineral was not well understood and the process was not able to give high recoveries, or at least, expected recoveries.
Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. 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.
05/04/2017· Top slicing permits high recovery of ore with little dilution under conditions where any method of mining from the bottom upward would be difficult, hazardous, and costly. Small stubs of ore between the ends of slices or between the end of a slice and the cave are sometimes lost, and 2 or 3 feet of ore may have to be left around
