Applications of electrochemical technology involving low reactant concentrations require electrodes with high mass transport rates and specific surface areas to increase cross-sectional current densities and optimise capital and operating costs. Experimental results will be compared with model predictions for two such reactor types, which facilitate adherent and coherent deposit morphologies: a) cathode feeder electrodes contacting unconsolidated beds of moving, conducting particles that can grow, and enable continual harvesting of the metallic product by hydraulic transport from the bed of the particles; b) mesh cathodes in fluidised beds of inert particles, to enhance mass transport rates; used for metal recovery from: i) low concentrations of platinum in aqueous iodide solutions; ii) acidic aqueous chloride solutions, produced by the leaching of waste electrical and electronic equipment, containing precious metals in low concentrations and base metals in high concentrations.
