MgO Depression in Ci-Ni Flotation - Froth Flotation ...

Froth Flotation (Sulphide & Oxide) ... Talc or other mineral such as serpentine of course makes a huge difference to the adopted strategy. Guar gum of course is well known talc depressant. (unknown) 3 years ago (unknown) 3 years ago. Like. CMC, guar and quebracho are all known talc depressants (if it is a talc issue you have). I have had success in depressing naturally floating talc with high ...

Presence of serpentine minerals hinders pentlandite flotation by slime coating in processing ultramafic Ni-ores. By experience it has been found that soda ash gives the best flotation recovery and grade for ultramafic ores. Soda ash is a pH modifier and considered to be a dispersant at the same time.

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE.

Flotation Research of Three Polymorph of Serpentine …

It is known that serpentine slimes coating on the sulphide surfaces are responsible for the poor metallurgy. Antigorite, lizardite and chrysotile are three kind of important polymorph of serpentine minerals. The three serpentine minerals usually accompany with Sulfide minerals, having ions with equal activities or similar properties on the ...

Flotation of chromite and serpentine - ScienceDirect

Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. A good knowledge of the flotation behaviour of chromite and the establishment of conditions for its selective separation from the gangue minerals might help the future exploitation of chromite deposits.

v115n8a4 Effects on entrainment of serpentines by ...

Serpentine minerals, which have the generalized composition (Mg,Fe)3Si2O5(OH)4, can be easy to crush and grind due to their convoluted and bent layered structures. These serpentines can hinder the enrichment of some metallic minerals and dilute their concentrates by entrainment during flotation. The resulting high pulp viscosities, slime coatings, and high content of dissolved ions adversely ...
