How silver is made material making history used The extraction of gold and silver from ore by the cyanide
Silver was first obtained in sixteenth century Mexico by a method called the patio process It involved mixing silver ore salt copper sulphide and water The resultant silver chloride was then picked up by adding mercury This inefficient method was superseded by the von Patera process fhe ore was sampled and this sample divided into eif ht portions The first part was crushed until all went throu h a 12 inch seive the second part was crushed until all went throu ha 30 inch seive etc the ore was then assayed for Rold and silver After wei 173 hin tbe old and silver were parted by disso vin the silver in nitric ac
