Rcovery of gold in pyritic ores - mine-engineer

The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current gravity technology. That appears to leave froth flotation as still the best method of recovering the gold from pyritic ores.

US7488370B2 - Reducing cyanide consumption in gold ...

The best conditions seem to be to fine grind the initial ore/concentrate, only partially oxidise the finely ground material to @12%, keep the temperature to between 60-85 degrees C., and use a lime/limestone mixture to keep the pH level alkaline. Fine grinding already results in a decrease of cyanide consumption relative to unground product.
