“…Thus, a pioneer cylindrical electrochemical reactor with a threedimensional anode of lead pellets was used in the Nalco process for the production of lead alkyls [2]. Van der Heiden et al [3,4] reported the removal of metals from dilute A C C E P T E D M A N U S C R I P T solutions by fluidised bed electrolysis using a cylindrical configuration with many anodic compartments made of a diaphragm with a central wire as anode, which are symmetrically placed in only one cathode. Around each diaphragm six bar-shaped contact feeders are installed to supply the fluidised bed with current.…”

A tumbled‐bed electrochemical reactor was described and shown to function well in reclaiming copper from a dilute acid copper system. A sound electrodeposit was obtained routinely and may be conducive to a stable and low maintenance industrial application. Graphs which approximately represent operating cost‐capital cost trends have been presented and suggested as useful for future work in developing and comparing alternative waste treatment techniques.

“…Since the first demonstration of the application of the (monopolar) fluidized bed electrode (FBE) [1,2], this electrode system has been the object of considerable academic [3] and some industrial [4,5] interest. As with several other recent advances in electrochemical engineering, the FBE resulted from the adaptation of a well established device in chemical engineering to mass transport 0021-891X/84 $03.00 + .…”

The behaviour of a fluidized bed electrode of copper particles in an electrolyte of deoxygenated 5 x 10 -1 mol dm -3 NazSO4-10 -3 tool dm -3 H2SO4 containing low levels of Cu(II), is described as a function of applied potential, bed depth, flow rate, particle size range, Cu(II) concentration and temperature. The observed (cross sectional) current densities were more than two orders of magnitude greater than in the absence of the bed, and current efficiencies for copper deposition were typically 99%.No wholly mass transport limited currents were obtained, due to the range of overpotentials within the bed. The dependence of the cell current on the experimental variables (excluding temperature) was determined by regression analysis. The values of exponents for some of the variables are close to those expected, while others (for concentration and flow rate) reveal interactions between the experimental parameters. Nevertheless the values of the correlation coefficient matrix are low (except for the term relating expansion and flow rate), so that cross terms may be neglected in modelling the system at the first levet of approximation.
