Summary
editDescriptionLead poisoning in the smelting and refining of lead (1914) (Huntington-Heberlein pot).png |
English: Identifier: leadpoisoningins00hami (find matches) PLATE 4.— HUNTINGTON-HEBERLEIN POT. The pot is the lower half, the upper half consisting of the great hood and flue which is fitted over the pot during roasting. The windows in the side are opened for raking from time to time. When roasting is complete the hood is lifted off, the pot caught by a crane, tipped over, and the smoking charge dumped and crushed. HUNTINGTON-HEBERLEIN POTS. This method of roasting and sintering ores was developed in
Europe and introduced into this country in 1905. The general
design of these furnaces is shown in the accompanying illustration (plate 4). The charge to be roasted is placed in a huge cast-iron pot which has a false bottom. If the first layers of the charge are red-hot, the roasting begins the moment the blast is turned on beneath the grate; otherwise a coal or coke fire must be started in the bottom before the charge is dumped in. |
