Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc.

There are two standard methods for extracting gold from electronic scraps: burning off the gold using high temperatures, which is energy intensive, expensive, and releases toxic gases. The second way involves leaching chemicals like a cyanide solution, which is also expensive and toxic, plus the remaining waste cannot be recycled.
