Figs. 13 and 14 show how the rate of the emulsion breakdown increases at higher electical field intensities. At high voltages; there is a critical point; above which the rate increases considerably. At the same field strength; increasing frequencies yield a faster and more complex breakdown. After separating the phases; the organic as well as the stripping phases can be recycled. The results of our experiments show that the LMT is suitable for a nearly complete and very selective metal recovery; especially from solutions which contain very low metal concentrations. The extraction and emulsion breakdown can be carried out continuously; and the expensive carrier; organic solvent; tenside and stripping phase can be recycled. Therefore; it is expected that the LMT works economically and with a low environmental pollution. The financial support of the Federal Ministry of Research and Technology is greatly acknowledged;
