    Abstract: Methods for purifying one or more value materials are provided. The method can include contacting an aqueous mixture comprising a value material and a contaminant with a dispersant and a depressant to produce a treated mixture. A weight ratio of the dispersant to the depressant can be from about 1:1 to about 30:1. The method can also include recovering a purified product comprising the value material from the treated mixture. The purified product can have a reduced concentration of the contaminant relative to the aqueous slurry.

    Abstract: The invention relates to a flotation agent for phosphate ore, which contains a fatty acid as a collector and alkoxylated alkylphenols as dispersing agents. Said flotation agent is characterised in that the alkylphenols are composed of a) 8 to 20 % by weight of one or more dialkylphenols wit alkyl residues having 8 to 12 atoms of C, and b) 80 to 92 % by weight of one or more monoalkylphenols with alkyl residues having 8 to 12 atoms of C, said alkylphenols being alkoxylated with 2 to 6 mol ethylenoxide.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining a copper pure ore with low As quality by efficiently separating an arsenic mineral from a copper material containing arsenic such as a copper ore or a copper pure ore.
    SOLUTION: A floatation step comprises crushing a copper material containing arsenic, adding water for slurrying, and adding a flotation reagent comprising an inhibitor, a foaming agent, and a collector and blowing air to the thus obtained slurry, wherein a chelating agent such as polyethylene amines is used as the inhibitor. Particularly when triethylenetetramine is used as a chelating agent, it is preferable to add 1 to 10 equivalents of triethylenetetramine with respect to the amount of soluble copper generated by oxidation of the copper material and it is more preferable to adjust the pH of the slurry before flotation to 7 or more and 8 or less.

    Abstract: In accordance with the present invention, there is provided a method of improving the separation of mineral values from their associated gangue. The method itself involves the addition of an effective amount of a treatment reagent to the froth flotation process which enhances the ore recovery. The treatment reagents of the method of the present invention comprise water-soluble organophosphonates which when added to the flotation feed slurry enhance the recovery of ore values therefrom. The organophosphonate treatment reagent may be used alone or in combination with a polymeric dispersant.
