Claims (1)

Patent-Ansprüch:Patent claims: Verfahren zur directen und vollständigen Entsilberung von Werkblei, darin bestehend, dafs an Stelle des bisher gebräuchlichen Zinks ein und dieselbe Menge einer Zinkaluminiumlegirung wiederholt in den flüssigen Werkbleisatz eingerührt wird, um dadurch eine Oxydation des Zinks zu hindern und eine Abscheidung der im wesentlichen nur aus Zink und Silber bestehenden Legirung zu bewirken.Process for the direct and complete desilvering of lead, consisting of that instead of the zinc which has hitherto been used, one and the same amount of a zinc-aluminum alloy is repeatedly stirred into the liquid working lead, thereby causing oxidation to prevent the zinc and to cause a separation of the alloy, which consists essentially only of zinc and silver.
