Gold Recovery 101 - Sepro Systems

The crushing, grinding and gravity portion of this process is essentially the same as the free-milling process discussed above. Instead of cyanide leaching of the cyclone overflow, the gold and sulfide minerals are recovered by flotation. The particles in the cyclone overflow are mixed with chemical

free circulation of the leaching agent. The leaching period is 2 – 4 days and gold recovery lies in the order of 70 – 80%. The cheapest but slowest technique is heap leaching. It is a process usually applied to low grade gold ore. Basically the ore is piled to a given height on an inclined impermeable surface, a so called leach pad.

crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation of sulphide

GOLD AND SILVER

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.
