Abstract
6866. Highfield, r. W. March 18. Dry processes for extracting lead; matte processes for copper. - In the reduction of complex sulphide ores, the ore is first roasted and thereafter a reducing - atmosphere is formed in the furnace, and the charge is heated electrically to obtain metal and matte. The lead is run off and cupelled, preferably in au electrically - heated hearth, and the residual matte is further heated by means of a direct current. At starting, a charge of ore and limestone is desulphurized by means of a blast injected through tuyeres G, whereupon a reducing - atmosphere is formed in the furnace by adding coke to the charge. Three - phase current is now supplied to the electrodes D, the blast is cut off, carbon and iron are added to the charge, and the temperature raised to 950‹ C.; the rotation of the molten charge caused by the current may he increased by the use of auxiliary electrodes. The zinc content is volatilized and condensation in the form of oxide is facilitated by the action of an electric discharge. The temperature is now increased and current may be supplied to the electrodes F, F<2> to effect a partial separation of the iron and copper in the matte. The upper part is then run off, and the remainder treated to extract the copper. The litharge resulting from the cupellation of the lead, and the zinc oxide from the condensation tower, are both reduced eventually on a bed of carbon heated electrically.
