MOLTEN SALT ELECTROLYTIC CELL AND METHOD FOR PRODUCING ZINC

摘要

Zinc and chlorine are produced from zinc chloride by using an electrolytic cell which comprises positive and negative electrodes standing upright or inclined, a gas collecting portion arranged above the electrodes, and a zinc reservoir arranged below the electrodes. The electrolytic cell can produce zinc and chlorine at a low electrolytic voltage, namely with a smaller electric power consumption. Zinc as a product is separated from the zinc chloride, i.e. a raw material, due to the specific gravity difference between zinc and zinc chloride, and is collected in the zinc reservoir, while the produced chlorine goes upward as a gas. Accordingly, zinc and chlorine can be efficiently separated by electrolysis.
