Heap cyanide leaching is applied for low grade (grading 3%) gold ore, ore powder, beneficiation tailing and leaching residue. It suits for large handling amount and various gold material of different grade. The process CIP/CIL/RIP, originated from CCD, are the mainstream methods, with leaching rate of 98% for easyleaching gold ore.
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH
