Rcovery of gold in pyritic ores - Mine Engineer.Com

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.

Gold-Pyrite ores - Danafloat - Home

Consequently, gold flotation recovery requires a focus on floating the associated base metals (predominantly lead, copper) and often pyrite minerals. While lime is often used in base sulphide mineral flotation, because excess lime also tends to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold recoveries. Natural pH is recommended for gold flotation.

Pyritic Smelting at Deadwood: A Temporary Solution to Refractory Ores DAVID A. WOLFF The recovery of gold from the matrix in which it is found has occupied the efforts of mining men ever since the discovery of the precious metal. Often, the success or failure of recovery pro-cesses has determined whether a mining town has lived or died.

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.

Flotation kinetics of a pyritic gold ore - ScienceDirect

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 is more sensitive to variation of P 80.
