  • Separation of manganese from brine
    Patent number: 9534276
    Abstract: A method for the selective precipitation and recovery of manganese from a manganese containing solution, such as a geothermal brine is provided, wherein the geothermal brine is contacted with ammonia, an ammine, or ammonium salt at a pH of greater than about 8.0 to selectively precipitate manganese having a purity of at least about 95%. Also provided are methods for the selective recovery of manganese and zinc from a brine solution.

  • Selective recovery of manganese, lead and zinc
    Patent number: 9238851
    Abstract: This invention relates to a method for the selective recovery of manganese and zinc from geothermal brines that includes the steps of removing silica and iron from the brine, oxidizing the manganese and zinc to form precipitates thereof, recovering the manganese and zinc precipitates, solubilizing the manganese and zinc precipitates, purifying the manganese and zinc, and forming a manganese precipitate, and recovering the zinc by electrochemical means.

  • Printable igniters
    Patent number: 7834295
    Abstract: An igniter comprises at least two conductors in the spaced-apart configuration and an electrically conductive layer bridging the at least two conductors, wherein the conductive layer has an electrical resistance greater than an electrical resistance of the at least two conductors. In one embodiment, the at least two conductors and the electrically conductive layer comprise a conductive ink, which may be the same conductive ink having different dimensions. A supplementary initiator composition may be deposited on or incorporated into the conductive layer. In a process for producing the igniter, the electrically conductive layer and the at least two conductors are printed on a non-electrically conducting substrate.
