Nickel flotation

Jun 01, 2018 The best flotation result was for the S ore sample where nickel upgraded from 3.0% up to 4.2% (i.e. by 40%) at around 70% when HDMA was used. This is considerably better than nickel flotation grade and recovery data reported in the literature for this type of ores (i.e. saprolite) . Based on these data, the best condition to upgrade nickel in

    The Application of High Intensity Flotation Technology

    Conventional flotation technology has historically failed to achieve high recoveries when treating 15 μm particles (Lynch et al, 1981). The new StackCell™ flotation technology was developed to specifically target this particle size range, and was tested at pilot plant scale at Mt Keith Nickel Concentrator

    Examination of Flotation Reagents Suitable for Nickel

    The flotation target was a higher nickel recovery from a concentration grade of 4% nickel and 35% iron. Sulphide ore is mainly associated with the following minerals pyrrhotite, pentlandite, chalcopyrite and pyrite. Pentlandite is the most abundant sulphide mineral and is the main nickel mineral in almost all nickel sulphide deposits [4, 5, 6]

    Enhanced methods for nickel recovery from low-grade ores

    The second stage of froth flotation produces a nickel concentrate of 10-20% Ni, along with other by-products and gangue. Smelting is the next stage, designed to recover as much metal as possible. Flash smelting is a common method: dry concentrates are fed into

    A New Process for Cobalt Nickel Separation

    This combination of flotation and smelting effectively removes most of the deleterious impurities, and thus produces a nickel-cobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way; however, not all sulphide ores
