In the refining of lead these furnaces are an important link in the sequence of recovering the gold and silver. They are both quite neat in operation, and with proper draft and ventilation should give no offense. The rich amalgam of zinc and lead in chunks is dropped into the retorts in the Fabre du Faur tilting furnace and the condensers sealed on at the neck of the retort. At the close of the distillation, when the zinc has been volatilized, the condenser is removed and the rich lead poured out and wheeled to the cupelling Text Appearing After Image: PLATE 13.— FABRE DU FAUR ZINC DISTILLATION FURNACE. The retort is shown with the zinc condenser in place. When this is removed the rich lead or doré runs out. There is no hood to catch the fumes. furnace, into which it is poured. From the cupels the dore, silver and gold, is recovered, the lead is oxidized to litharge, and the arsenic and antimony are lost in the fume. |
