  8. Pattinson's process - Wikipedia

    en.wikipedia.org/wiki/Pattinson's_Process

    Pattinson's process or pattinsonisation is a method for removing silver from lead, discovered by Hugh Lee Pattinson in 1829 [1] and patented in 1833. The process is dependent on the fact that lead which has least silver in it solidifies first on liquefaction , leaving the remaining liquid richer in silver.
