  • Patent number: 7648643
    Abstract: A process and composition of matter for the recovery of metal from a metal-laden ore, soil or rock is provided. A liquid, non-toxic, low pH acidic composition is used as a chelating agent that extracts the metal into a pregnant liquid solution. The pregnant solution is treated by known conventional means, such as filtration, centrifuging, or electrolysis to remove the extracted metals. The low pH, acidic composition (LpHAC) does not have any known toxicity to man or the environment and performs as an ideal fluidized reaction metal extractant. As a metal extracting agent, it effectively and efficiently extracts gold and other metals from ore laden soil or rock with no environmental and negative health impact.

  • Patent number: RE41109
    Abstract: A composition of matter and the method of making that provides a low pH acidic composition that is useful for destroying microorganisms that are undesirable and useful for destroying or reducing melanomas on human skin. The composition and method include sulfuric acid combined with distilled water and ammonium sulfate under at least 15 psi pressure in a pressurized container, all of which is heated to approximately 800° F. or more for at least 3 hours. The final cooled mixture is stabilized with 10 percent of the original mixture. The resultant composition is useful for preserving food, such as fresh fish, and for skin treatment of melanoma and as bactericides, fungicides, or viricides.
