Use of the CESL Process for PGM Recovery
摘要
NewRange CopperCopper NickelNickel is developing significant copperCopper, nickelNickel, cobaltCobalt and platinumPlatinum group metalMetals (PGM)Platinum Group Metals (PGM) resources in northeastern Minnesota’s Duluth Complex. One aspect of NewRange’s future plan could include using the CESLCESL process to treat bulk nickel concentrateNickel concentrate to produce refined metalMetals products, including a PGMPlatinum Group Metals (PGM) concentrate in order to improve economics associated with these critical minerals. This presentation will discuss the opportunity for PGMPlatinum Group Metals (PGM) recovery using the CESLCESL process, including flowsheet developmentFlowsheet development, related testingTesting of the CESLCESL process, challenges around the PGMPlatinum Group Metals (PGM) recovery circuit and sulphurSulphur by product handling, and additional work required to derisk the process.
