Abstract

The invention discloses an electrothermal copper-smelting slag depleted furnace, which comprises a furnace body, supports, an oxygen lance and electrodes; the furnace body comprises a furnace shell defining a furnace chamber and a refractory material layer arranged on the inner wall of the furnace shell, the furnace body is provided with a feed inlet for feeding copper-smelting slag and vulcanizing agent into the furnace chamber, a siphon inlet for discharging copper matte, a waste slag-discharging outlet, electrode plugholes, a smoke outlet and an oxygen lance plughole, wherein the oxygen lance plughole is formed at the bottom of the furnace shell; the furnace body is supported by the supports; the oxygen lance is plugged into the oxygen lance plughole; and the electrodes are plugged into the furnace body via the electrode plugholes. When the electrothermal copper-smelting slag depleted furnace is used for bottom-blowing electrothermal copper-smelting slag depletion, the copper content in waste slag can be reduced, and electricity consumption can be decreased.

Description

technical field [0001] The invention relates to an electrothermal depletion furnace for copper smelting slag. Background technique [0002] At present, in order to reduce the blowing load, large-scale copper smelters using advanced smelting technology all adopt higher copper matte grades, that is, the output copper matte grades are higher, and the copper content in the higher-grade copper matte is 50%. In the range of ~70%, the copper content of copper smelting slag fluctuates in the range of 2% ~ 8%. [0003] In order to recover the copper in the copper smelting slag, the copper smelting slag is traditionally depleted by an electric furnace. The copper smelting slag is added to the electric furnace, and the copper smelting slag is heated by electrode heating so that the copper in the copper smelting slag settles in the form of copper matte. Come down and separate from the waste residue. [0004] The furnace body of the traditional depleted electric furnace has a feeding p...
