RETICULATE ELECTRODE FOR RECOVERY OF METAL IONS AND METHOD FOR MAKING

摘要

A cathode for use in an electrolytic cell for recovering metal from solutions containing ions of the metal including a conductive reticulated support and a carbon impregnated conductive polymeric foam or mat attached to the support and in substantial electrical contact with the support. Conductivity of the polymeric foam or woven cathode should generally be greater than about 10,000 ohms per centimeter, and preferably greater than 5,000 ohms per centimeter with preferable materials averaging 3,000 ohms per centimeter or greater.
