    Contents Coppernickel alloys, properties and appliions

    The coppernickel alloys are single phased throughout the full range of compositions and many standard alloys exist within this range, usually with small additions of other elements for special purposes. The two most popular of the copperrich alloys contain 10 or 30% of nickel.

    An experimental technique for the differential flotation of bulk sulfide concentrates from Duluth Gabbro into copper and nickel concentrates is described. The technique utilizes a twostage bulk sulfide flotation procedure to obtain a copper concentrate that analyzed 25 percent copper and percent nickel, and a nickel concentrate that analyzed 10 percent nickel and about 1 percent copper.

    The ore is processed through a conventional flotation concentrator that consists of a simple crushing and grinding circuit, rougher, scavenger and cleaner flotation cells, followed by concentrate and tailings thickeners. The end product is a nickelcoppercobaltPGM concentrate, which is sold to Jinchuan Group for smelting.

    Coppernickel is widely used in high pressure systems operating at over 105 bar (~1500 psi) and especially where there is an additional need for corrosion resistance or low temperature capability. The ease of forming of the alloys into complex fittings and coils have ensured their continued selection.

    Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.
