cyanide extraction process of silver from argentite ore

The chief ore of silver is argentite and silver is extracted from argentite by the hydrometallurgy process. Firstly, the silver ore is dissolved in cyanide solution to produce a soluble argento cyanide complex from which the metal can be obtained by the reduction method. The different steps involved in the extraction of silver are as follows: a.
