APPARATUS AND PROCESS FOR PRODUCING BLISTER COPPER

摘要

Fire-refined blister copper is produced from copper concentrate by a process comprising: (A) melting and oxidizing the copper concentrate in a smelting furnace (17) to produce molten matte and slag, and to separate one from the other; (B) removing the molten matte from the smelting furnace (17); (C) solidifying the molten matte; (D) injecting the solidified matte into a converting furnace (33) in which the matte is converted to blister copper and slag; and (E) transferring the blister copper from the converting furnace to an anode furnace (47a and 47b) to produce fire-refined blister copper. After the fire-refined blister copper is produced in the anode furnace, it is typically transferred to an anode casting wheel (66) on which it is converted to copper anodes suitable for subsequent electrolytic refining to cathode copper.
