| Abstract: |
| Industrialization application and development, operation conditions and technical parameters of Two-Step Copper Smelting Process developed by Dongying Fangyuan Nonferrous Metals Co., Ltd were introduced. Raw materials including concentrates and flux are simply mixed without pretreatment are fed into Submerged Lance Smelting Furnace (SLS). High grade and hot white matte from SLS is charged to Submerged Lance Converting Refining Furnace (SLCR) via matte conduit. Two SLCRs work in turn to produce anode copper to maintain continuous operation of whole production system. This new technology was put into production in October 2015 with capacity of 1.75 Mt/a of mixed minerals. |
