  • How silver is made material, making, history, used

    BackgroundThe Manufacturing ProcessThe FutureSilver was first obtained in sixteenthcentury 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sulphide, and water The resultant silver chloride was then picked up by adding mercury This inefficient method was superseded by the von Patera process In this process, ore was heated with rock salt, producing silver chloride, which was leached out with sodium hyposulfite Today, there are several processes used to extract silver from ores A method called the cyanide, or he
