What is the formula of gold III cyanide ...
2020-6-21 A sodium cyanide solution is commonly used to leach gold from ore. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.

The Chemistry of the Extraction of Gold - SAIMM
2011-5-29 All known gold(III) complexes have the low-spin 4P45d8 electronic con figuration and are also diamagnetic. The preferred co-ordination number of gold(I) is 2 and that of gold(III) is 4, with gold(I) tending to form linear complexes and gold(III) tending to form square planar complexes. For example, the cyanide complexes of gold(I)

Extraction of Gold
The gold is deposited on the lead, and after removal of this metal still contains a considerable proportion of both lead and silver. It is freed from them by the operation called " parting." Access of air is essential to solution of gold in potassium cyanide, the process being attended by evolution of hydrogen.
