The pilot ‘Metal purification to battery grade sulphides’ focuses on the dissolution of hydroxide and sulphide metal precipitates followed by solvent extraction and crystallization for the production of ultra pure battery-grade metal sulfates (CoSO4, NiSO4). The pilot consists of a leaching reactor, 20 stages of mixer-settlers (SX Kinetics). The leaching reactor was designed and constructed in collaboration with HiTec Zang, and consists of two heatable glass mixing reactor chambers of size 1 L and 5 L, both coupled to a glass filtration unit. The 20-stage mixer-settler battery was designed and constructed by SX Kinetics, with peristaltic pumps supplied by Cole-Parmer. The mixing and settling chambers are both constructed of glass, with a volume of 270 mL and 1000 mL respectively. The stages are connected counter-currently with polymeric tubing. The flow of organic and aqueous solutions through the mixer-settlers is controlled by the peristaltic pumps, with flow rates up to 10 L/h. Only room temperature experiments are possible.
