flotation separator for pyrite ore

  • A novel depressant for selective flotation separation of

    The sample used in this study is a special pyrite ore which contains pyrophyllite. There are only a few investigations about flotation separation of sulfide minerals from pyrophyllite . It is important that the use of glucan as a potentially commercial depressant for the flotation of pyrite ore has not been studied previously.

  • Selective flotation of chalcopyrite from pyrite using

    Therefore, the separation of chalcopyrite from pyrite has always been a challenge in mineral processing field. The screen or design of more selective depressants and collectors is the key to efficient separation. Pyrite flotation depressants can be divided into inorganic and organic ones. Inorganic depressants include lime, sodium sulfide

  • Galena Sphalerite Flotation Separation Method

    If a pyrite concentrate is required, this can usually be obtained by sending the tailing of the zinc flotation section direct to a third stage, where the iron sulphides are floated with the addition of 0.050.15 lb. per ton of pine oil and 0.10.2 lb. of ethyl and/or amyl xanthates, the

  • The flotation separation of pyrite from serpentine using

    Compared to the flotation of bare pyrite, the flotation recovery of pyrite decreased significantly with increasing pH from 3.0 to 11.0 when 0.2 g/L serpentine was added prior to the addition of collector, and a maximum decrease was obtained with the pyrite recovery of 14% at pH 9.0, which was similar to the observations of Zhang et al and Feng

  • EP0568672B1 Flotation separation of arsenopyrite from

    Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings

  • Pyrite Mining Processing Equipment Flow Chart Cases

    Flotation Separation As flotation also can be used for pyrite ore separation, though flotation separation has deficiency with considerable large investment in equipment, higher mining cost, while better efficiency and index in mining with simple flotation reagents, so flotation methods can be used for low grade pyrite ore.
