Cyanidation of a pyrrhotite-bearing gold ore

2015-12-27  cyanidation and the pre-leaching used the same pulp. The pH was controlled by lime addition. The cyanidation tests were 32h or 48h in duration. Relative to the average concentration, the accuracy of free cyanide concentration was ±10%. The gold extraction was based on the gold content in the leached tails compared with the gold content in the head
