    Precipitation Of Gold From Aqueous Cyanide Solutions posted in Student Hi everyone Could you please explain why the precipitation of gold from aqueous cyanide solutions is not thermodynamically spontaneous And Why is electrowinning required to precipitate gold out of cyanide solutions Thank yougold/silver precipitation from dilute sodium cyanide solutions and is favoured for gold cyanide containing high silver concentration MINTEK researchers suggested that zinc cementation should be considered as a process alternative to electro winning for direct treatment of carbon eluate in the CIP process (Miller, 1981) The ore is leached before going through zinc precipitation Zinc precipitation on gold recoveryCyanide Use in Gold MiningEarthworks Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads The cyanide dissolves the gold from the ore into the solution as it trickles through the heap The pad collects the now metalimpregnated solution which is stripped of gold and resprayed isolation of gold from silver using cyanide
