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. ... I think that you need a number of strategies to successfully remove talc from nickel and copper sulphide concentrates, since 22-24% MgO is a lot of talc.

Copper-Nickel ores Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite. Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed.

A low-grade disseminated nickel sulphide serpentinite ore from W.A. had a relatively high permeability after drying. Various techniques indicated that the permeability resided within a fine network of fibrous vein- lets and especially within coarse cracks along which the sulphides lay. The ore minerals were therefore open to selective extraction by chemical leaching.

Jun 05, 2017· 1. Introduction. Serpentine is a typical alteration product of pyroxenes or olivines during hydrothermal metamorphosis , which seriously interferes with the concentration of pentlandite in the froth flotation of copper–nickel sulfide ore.The mechanisms by which serpentine affects the flotation behavior of pentlandite include entrainment , physical entrapment and hetero-aggregation (so-called ...

copper-nickel sulphide ores is stage-wise flotation. The first flotation stage concentrates mainly copper minerals. The copper middling is re-floated to obtain nickel concentrate. During the industrial process of copper-nickel ore, it was observed that significant amount of nickel sulphides was lost to the tailings during the nickel flotation.

3 1Nickel Sulphide Resources ... conventional flotation process on low-grade disseminated sulphide ores tends to be difficult due in large part to fines containing magnesium-rich serpentine type minerals which generate slimes during comminution.

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 surface, which makes the flotation separation difficult.
