Abstract:

This article carried out an experimental study on the ammonia-cyanide column leaching of a carbonate rock gold deposit containing copper.It studied the particle size，the ammonia cyanide ratio，the irrigation rate and the eluent composition and so on，on the influence to the column leaching effect.The results show that when the particle size is -20 mm，the effective ammonia cyanide ratio is 2∶1，and the irrigation rate is 5 to 10 L/（m2·h），the leaching rate of Au will reach 82.06%， but the leaching rate of Cu is only 7.85%，the consumption of main leach- ing agent NaCN dropped from 15 kg to 4.24 kg per ton ore，and the NH4HCO3 correspondingly needed 35.33 kg per ton ore.Additionally，compared using water as the solvent of leaching agents with using the copper-containing barren solution as the solvent，it did not affect the leaching rate of Au，but the leaching rate of Cu decreased by 79%.

Key words: Copper bearing gold ore, Ammonia-cyanide column leaching, Ammonia cyanide ratio, Irrigation rate
