THE METALLURGY OF ANTIMONY. 83 a reverberatory furnace), as used iu New Brunswick, are as follows:— Length 42' 6" Width . . . . . . . . 7' 6" Working doors on each skie . . . . , 10 Height from bed to roof 2' 1" Width of fire-grate 2'1" Height of fire-bridge 5'2" Breadth of fire-bridge 1" The method of working is as follows :— Capacity of furnace . . . . . . 30 cwta. Charges . . . . . f» to o ewts. at one time. S charges (18 cwts.) during 24 hours, so that each charge remains in the furnace for 40 ! hours. Consumption of) m. A . -,.«,, wood j" Three-quarters of a cord m 24 hours. Loss of Sb 7*5 percent. The ore must be strongly heated, and thoroughly rabbled every five minutes during the last two hours before being drawn. Properly roasted ore must have a dull grayish-yellow colour. The furnaces, as used at Banya, have the following dimensions:— Length . . . . * 26' 3" Width 6' 6" Working doors on each side 5 Ores roasted in 24 hours 24 cwts. Charges of 4 cwts. each are introduced at the colder end of the furnace, and are then finally drawn after twenty hours at the opposite end. Stepped grate is used, and the fuel is lignite. The following operation for roasting the ore is carried out in Tus % cany, Italy:—200 kilos, are charged into a reverberatory furnace, heated up a little previously. The temperature is then raised to not more than 350°. Rabbling is carried on for from three to twelve hours. Rich ores require a longer time. Each operation requires 35 kilos, of lignite, and the loss due to volatilisation is not more than from 5 to 8*5 per cent. Another type of the same kind of furnace is shown in figs. 19, 20, 21, 22. Furnaces with a trough-shaped bed sloping towards one of the longer sides of the furnace have been proposed for the performance of both reduction and roasting at the same time. The use of having the slope is for the tapping off of any portion of the sulphide tliat is unavoidably liquated during the roasting.
