Solved Problem

Copper matte bottom-blowing continuous converting process (BCC) is a new continuous copper converting process independently researched and developed by TOMINE based on the SKS/BBS process. The BCC furnace is also of horizontal type. Oxygen-enriched air is blown into furnace via lances positioned at the furnace bottom to react with copper matte to produce blister. BCC furnace operates continuously, thus causing less fugitive offgas with stable volume. Besides, heat intensity of converting process is high and furnace body heat loss is less. Moreover, spent anode from refinery can be fed directly into the BCC furnace, which helps to lower operating cost. Based on the BCC process, the Highly-efficient and Environmental-friendly Copper Smelting Process with a Compact Set of Three-in-series Furnaces by cycles so that converting and fire-refining are completed in the same one BCC furnace, thus further shortening the process flow. By December of 2017, the BCC process has been commercialized in seven smelters.
