  • Continuous process for the preparation of manganite, MnOOH
    Patent number: 4448760
    Abstract: A process of preparing manganite, MnOOH, from an aqueous manganese (II) nitrite solution by a continuous two-step decomposition process in the presence of an "active" solid surface.
    Type: Grant
    Filed: September 30, 1982
    Date of Patent: May 15, 1984
    Assignee: Chemetals Incorporated
    Inventors: Jay Y. Welsh, Denis F. DeCraene, Irving Sochol
  • Preparation of manganous chloride solution
    Patent number: 4173617
    Abstract: A method for the preparation of manganous chloride solutions using copper as a redox intermediate in the reaction between manganese and chlorine. Treatment of manganese-containing materials with a copper solution results in oxidation and dissolution of the manganese and the formation of elemental copper. The copper is in turn dissolved by reaction with cupric or ferric ions, which are then regenerated by chlorine oxidation.
    Type: Grant
    Filed: February 23, 1978
    Date of Patent: November 6, 1979
    Assignee: Chemetals Corporation
    Inventors: Jay Y. Welsh, Irving Sochol
  • Preparation of manganese/cobalt bromide
    Patent number: 4138354
    Abstract: A method for the preparation of manganese bromide and cobalt bromide using a manganese/cobalt redox system. Elemental manganese is reacted with a solution of cobalt bromide, forming manganese bromide and elemental cobalt. Subsequent reaction of the cobalt with bromine, and alternate additions of manganese and bromine, can be used to produce a wide range of Mn:Co ratios in the solution.
    Type: Grant

  • Recovering metal values from marine manganese nodules
    Patent number: 4123499
    Abstract: A method for selectively extracting metal values from manganese bearing ores such as marine nodules. The ore is initially leached to solubilize manganese and other desirable metals as nitrates. The resulting solution is then treated with manganous hydroxide to selectively precipitate metals such as copper, nickel and cobalt. The enriched mixture of metal hydroxides is separated from the manganese nitrate solution, which is decomposed to recover high purity MnO.sub.2.
    Type: Grant
    Filed: May 20, 1977
    Date of Patent: October 31, 1978
    Assignee: Chemetals Corporation
    Inventors: Jay Y. Welsh, Irving Sochol
  • Preparation of alkali metal cyanates
    Patent number: 4000249
    Abstract: Process for the preparation of alkali metal cyanate by the reaction of urea and alkali metal carbonate. The addition of water to the reaction in an intermediate step activates partially blocked alkali metal carbonate and provides an alkali metal cyanate product of high purity.
    Type: Grant
    Filed: January 15, 1976
    Date of Patent: December 28, 1976
    Assignee: Diamond Shamrock Corporation
    Inventors: Irving Sochol, Jay Y. Welsh
  • Preparation of manganous hydroxide
    Patent number: 3950505
    Abstract: Manganous oxide is converted directly to manganous hydroxide by hydration in the presence of a catalyst. The product has high purity and reactivity.
    Type: Grant
    Filed: April 28, 1975
    Date of Patent: April 13, 1976
