  • Reduction leaching of raw sea nodules with sulfides
    Patent number: 4085188
    Abstract: A process for extracting metal values from sea nodules is provided in which nickel, cobalt and copper values are selectively extracted by leaching raw sea nodules in an aqueous ammoniacal medium in the presence of a reducing agent for tetravalent manganese and carbonate to precipitate the reduced manganese as manganous carbonate.
    Type: Grant
    Filed: March 8, 1976
    Date of Patent: April 18, 1978
    Assignee: The International Nickel Company, Inc.
    Inventors: Kohur Nagaraja Subramanian, Gerald Vernon Glaum
  • Two stage leaching of limonitic ore and sea nodules
    Patent number: 4065542
    Abstract: A process which enables cumulative recovery of nonferrous metal values from manganiferous sea nodules and a limonitic ore comprises treating the limonitic ore in an aqueous acidic medium under reducing conditions to extract nonferrous metals and iron from the ore and form a solution containing ferrous iron and then leaching the sea nodules with such solution to extract nonferrous metals from the sea nodules and precipitate a predominant amount of the iron as hydrated ferric oxide.
    Type: Grant
    Filed: May 19, 1976
    Date of Patent: December 27, 1977
    Assignee: The International Nickel Company, Inc.
    Inventors: Kohur Nagaraja Subramanian, Gerald Vernon Glaum
  • Reductive leaching of limonitic ores with hydrogen sulfide
    Patent number: 4062924
    Abstract: A process is provided for extracting iron values as soluble ferrous salts from a limonitic ore which comprises leaching the ore in an acidic medium in the presence of a reducing agent, the reducing agent being a sulfide. Non-ferrous metal values are also extracted from the ore and they may be selectively separated from the solubilized iron salts.

  • Two stage sulfuric acid leaching of sea nodules
    Patent number: 4046851
    Abstract: A process for extracting metal values from manganiferous sea nodules is provided in which nickel, copper, and cobalt values are selectively leached in a sulfuric acid medium in two stages, the first stage being effected at a temperature up to about 100.degree. C and to a final pH of not less than about 1.5 and the second stage being effected at a temperature of about 160.degree. C to about 260.degree. C and at an initial pH of not less than about 1.5.
