Abstract:
Two-step copper smelting process (hereinafter Fangyuan process) has been recently developed and patented by Dongying Fangyuan Nonferrous Metals Co., Ltd. and Shandong Fangyuan Nonferrous Metals S&T Co., Ltd ((hereinafter Fangyuan Company). This is the first and only process of this kind to directly produce anode copper by two steps in the world. This new technology to produce anode copper from concentrate includes two steps and can be summarized below. The raw materials, including concentrates and flux, are simply mixed without pretreatment and fed into Submerged Lance Smelting Furnace (SLS). High grade and hot white metal produced by SLS is sent to Submerged Lance Converting Refining Furnace (SLCR) via matte conduit. Two SLCRs work in turn to produce anode copper in order to maintain continuous operation of the whole production system. The new technology started its operation in October 2015 with the capacity to treat 1.75 Mt/a mixed minerals proved with various advantages. This paper will describe the industrialization application and development process of new technology at Fangyuan Company, with detailed discussion about its operation conditions and technical parameters.
