The flotation of magnetic and non-magnetic pyrrhotite from

The non-stoichiometric sulfide mineralpyrrhotite(Fe (1− x) S), common to many nickel ore deposits, occurs in different crystallographic forms and compositions. A series ofpyrrhotitesamples derived from Canada, South Africa and Botswana whose mineralogy is well characterised, were selected here in order to develop the relationship between mineralogy andflotationperformance.

Pyrrhotite Depressant in Polymetallic Flotation - Froth

The number two depressant is lime. In general,flotationofpyrrhotiteis depressed in the range of aboutpH 9.3and above. Note that this is not just a pH effect - sodium hydroxide and sodium carbonate are not particularly effective. The third depressant is redox (eH). When the redox is low,pyrrhotiteis depressed.

Flotation-magnetic separation for the beneficiation of

Thecellvolume was chosen to obtain a 30% solid-liquid ratio, and the impeller speed was set to 1800 rpm. Sodium silicate, ethyl thiocarbamate, and EM-312 were added in sequence to float the sulfide minerals. The bulk fraction of the sulfideflotationwas the feed for the rare earthflotation. ...

Magnetic FlotationSeparator | Longi. Themagnetic flotationseparator is generally utilized in the finishingseparationstage. It was designed for use with ferromagnetic minerals having a susceptibility higher than 3000x 6 cm/g and has been found to normally increase the concentrate grade by 9% which can greatly increase the systems overall efficiency.

Magnetic separation of copper sulfideores containing copper and magnetite. Copper sulfide is the inorganic compound, is cupric sulfide, chemical formula is CuS, dark brown, very insoluble substance, is one of the most insoluble materials (after HgS, platinum sulfide, silver sulfide etc.), because its slightly solubility, makes some reaction that seemingly can't react can occur.
