  • Process for removing manganese from organic solutions of oximes and nickel ore treatment process
    Patent number: 6156280
    Abstract: Process for removing manganese values from a solution of a water-immiscible hydrocarbon containing manganese values and a water-insoluble oxime extractant capable of extracting nickel values from aqueous ammoniacal solutions comprising the steps ofI) contacting the water-immiscible hydrocarbon solution with a finely divided active metal and an aqueous solution of a strong acid to decrease or complete remove the manganese values from said water-immiscible hydrocarbon solution; andII) separating the stripped hydrocarbon solution from the aqueous solution.The invention also relates to a method for the extraction of nickel from nickel-containing ores in which a content of manganese values is present in which the above process is used.
