Improving gold recovery of Pb

Free gold and gold wrapped in sulfides are considered as the object of gold floatation. However, floatation of free gold exhibits more variables in practice. In this study, improving gold recovery of a Pb–Zn sulfide ore from Yunnan Province, China, was investigated.

Rcovery of gold in pyritic ores - Mine Engineer.Com

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 generally fine, ranging from 75 microns down to 2 or 3 microns.

Gold Mining Process Development

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

no other operational changes in the pyrite flotation operation. In either case, this operation served to recover as a saleable product, a material (pyrite) typically discharged as a component of waste. Currently, the operation of pyrite flotation is demand driven, with the pyrite circuit used only as needed to meet the demand for the pyrite product.

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 …
