recoveryof gold in pyritic sulfideores mine

Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This generally involves frother, several collectors (promoters) and possibly some modifying or depressing agents as well

mw mining inspections, inc. sulfide,sulfide,mining

Sulfide ores, and pyrites, have caused and continue to cause difficulty in recovering the gold values from these Carlin type deposit ores. In most instances, visible gold cannot be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, a high rate of visible specs of gold can be seen under microscopic

sulphide goldore treatment by leaching andflotation process

Problem withgoldrecovery fromsulphideore: How may a mill get the maximum recovery ofgoldfrom asulphideore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases agoldmill using an all-cyanide flowsheet with fine grinding of all the ore will report very lowgoldcontent in the tailings particularly on an

minerals gekko systems

Because cyanide cannot always leach sulphide-associated gold, regrinding the ore is typically required to expose the free gold for recovery by intensive leaching. Critically, the size at which one can efficiently liberate gold from the host mineral of the particle will determine the process to use for optimal gold recovery. Sulphide Gold Recovery. Pre-concentration of coarse 350 – 500 micron sulphide-associated …
