In the early days of mining, men would extract gold by placer mining, or by panning , Then the “cyanide leaching process” was developed Mixing the tailings with a cyanide solution, or simply spraying the tailings with a cyanide solution, would cause a chemical reaction to take place When gold and silver comes in contact with cyanide.
