In the leaching process, the Gold and Silver ore is leached with NaCN or KCN, cyanide ions. Let us take an example to understand this more clearly with reactions involved: Let us take silver sulphide, A g 2 S and add NaCN, Sodium cyanide solution to it. The reaction can be written as: Now the complex formed is water soluble, so we need a good

The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.
