Abstract
Two-step copper smelting process (hereinafter Fangyuan Process) has been recently developed and patented by Dongying Fangyuan Company. This is the first and only process of this kind to produce anode copper in the world. And it can be summarized as below. The raw materials including concentrates and flux are simply mixed without treatment and fed into Submerged Lance Smelting Furance (SLS ). High grade matte (>73% Cu) produced by SLS is sent to Submerged Lance Converting Refining Furnace (SLCR ) via matte conduit. Two SLCRs work in turn to maintain continuous operation. Anode copper from SLCR is sent to the casting wheel to get anode copper plates. The new technology started operation in October 2015 with a capacity to treat 1.5 Mt/a copper concentrate proved with various advantages. This paper will describe its development process at Dongying Fangyuan, with detailed discussion about the operation conditions and parameters.
