  • Patent number: 5019237
    Abstract: Both a method and apparatus to recover metal in a solid amalgamated form from waste heavy metal electrolye and to reduce the remaining substance to an inert material and distilled water. The hot electrolyte is sprayed through a direct current sparking corona discharge freeing positive and negative ions. Before they reunite they are blown with air and accelerated with polarized force fields at a non-conductive dividing hemisphere with polarity collecting plates on its sides that ions of the correct polarity take to hold to make up molecules. The blown hot ozone vapor laden air is channeled onto a condensing flue, where clean water is removed, and goes on into the next identical cell to repeat this process twice more ending with a scrubber. The electrolyte is cycled through the cells until depleted, when clean water is introduced and filtered. The substance filtered out is inert.
