  • Nickel processing Extraction and refining Britannica

    Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles.

    Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 68% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues

  • Froth flotation Wikipedia

    Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

    A process for beneficiating a finely ground ore containing sulfide minerals of copper and nickel by selective flotation to produce a copper concentrate and a coppernickel concentrate comprises pulping the ore with water to form a slurry, conditioning the slurry with an aqueous solution of SO 2 (H 2 SO 3) equivalent to from about 2 to about 4.5 pounds of SO 2 per ton of dry ore for a time

  • Sequential Selective Flotation Process Flowsheet

    A selective or sequential flotation flowsheet of two or more products. By utilizing selective flotation, two or more minerals in an ore are separated into individual high grade products. ORE TREATED: The most common of ores treated in this manner are lead zinc, copperzinciron, coppernickel, but application may be made to other two or three

  • The selective flotation of pentlandite from a nickel ore

    Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite.
