摘要
It has been shown that within a broad interval of the rates of the electrolyte flow in a fluidized bed of inert particles the mass transfer rate of electroreduction of ions of nonferrous metals varies insignificantly. Based on the constancy of the flow rate of the electrolyte in the bulk of the fluidized bed of inert particles we have proposed a simple correlation of mass transfer for conditions of uniform liquefaction. Correctness of the mass transfer equations with the account of accepted assumptions has been confirmed by the calculations of diffusion coefficients from the experimental data on the proposed correlation.
