Common Silver Extraction Methods Mining-pedia
Use cyanide-free or micro-cyanide process. Silver flotation process with no or less use of cyanide, which inhibits silver minerals or carrier minerals, is beneficial to the recovery of associated silver and has received extensive attention. More than 60% of lead-zinc-copper mines have applied this method and achieved good results. 2.

Why is silver extracted by the cyanide process? Quora
Many ores containing silver can be finely ground and when mixed with sodium or potassium cyanide in solution the silver will form the stable cyanide complex. For example, silver is frequently found as the sulphide (a stable compound and indeed the compound formed when silver tarnishes). This will dissolve in cyanide solutions to yield the complex.
