NOVELTY - The extraction method of gold/silver involves preparing gold/silver cyanide complex solution using gold/silver standard solution and cyanide solution, placing the oxidized graphene in gold/silver cyanide complex solution to adsorb the gold/silver cyanide complex for 5-50 hours, separating oxidized graphene, desorbing gold/silver cyanide complex from the oxidized graphene to extract gold/silver, and reusing the desorption of the oxidized graphene. USE - Extraction of gold/silver (claimed). ADVANTAGE - The method enables extraction of gold/silver by simple and economical process.
