N2 - Applications of electrochemical technology involving low reactantconcentrations require electrodes with high mass transport rates and specificsurface areas to increase cross-sectional current densities and optimise capitaland operating costs. Experimental results will be compared with modelpredictions for two such reactor types, which facilitate adherent and coherentdeposit morphologies: a) cathode feeder electrodes contacting unconsolidatedbeds of moving, conducting particles that can grow, and enable continualharvesting of the metallic product by hydraulic transport from the bed of theparticles; b) mesh cathodes in fluidised beds of inert particles, to enhance masstransport rates; used for metal recovery from: i) low concentrations of platinumin aqueous iodide solutions; ii) acidic aqueous chloride solutions, produced bythe leaching of waste electrical and electronic equipment, containing preciousmetals in low concentrations and base metals in high concentrations.
