The E Pyrite from Serpentine by Flotation

of sulfide minerals [6,7]. In view of this property of serpentine, some researchers have used serpentine. as an inhibitor for the flotation separation of galena and pyrite [8–10]. The cover of fine serpentine particles on the surface of target minerals is the main factor a ecting.

The flotation separation of pyrite from serpentine using

Nov 20, 2019 To address the problem of the flotation separation of sulfides from serpentine and other Mg-bearing silicate minerals, polysaccharide depressants such as carboxymethyl cellulose (CMC), N-carboxymethyl chitosan (N-CMC), guar gum have been used to disperse slime particles of serpentine from sulfide surfaces [6,,,].

(PDF) Flotation of chromite and serpentine

In sulphide ore flotation, the interaction between the valuable sulphide minerals and the gangues are complex. Serpentine, a common magnesium-bearing silicate mineral in sulphide ores, can largely...

Utilization of tetrasodium iminodisuccinate to eliminate

May 01, 2020 The adverse effect of serpentine on the flotation of sulfide minerals has been well proved ( Feng et al., 2012c, Feng et al., 2012d, Liu et al., 2018a, Peng and Bradshaw, 2012 ). In this study, IDS was selected to improve the flotation recovery of pyrite depressed by serpentine.

Effect of a novel phosphate on the flotation of serpentine

May 01, 2020 In the flotation process of serpentine-containing copper-nickel sulfide ore, serpentine slime coatings significantly reduced the flotation performance of copper-nickel sulfide. Sodium phytate is a highly effective dispersant for MgO control in the flotation of copper-nickel ore. Compared with traditional dispersant sodium hexametaphosphate, grade

The Effect of Sodium Alginate on Chlorite and Serpentine

Chlorite and serpentine are common magnesium-containing gangue minerals in copper sulfide flotation. In this study, sodium alginate, a natural hydrophilic polysaccharide, was introduced as a selective depressant for these gangue minerals. Micro-flotation tests were conducted on both single minerals and synthetic mixtures.

The Critical Role of Pulp Density on Flotation Separation

When the solid ratio of sulfide to serpentine was 1:1, lower pulp density (20 wt %) contributed to better rheological and flotation outcomes. Generally, the addition of SHMP (sodium hexametaphosphate) is beneficial to reduce the amount of serpentine mineral into the concentration as a depressant through changing the surface electrical behavior of serpentine.

Using oxalic acid to eliminate the slime coatings of

Apr 01, 2020 Thus, more comprehensive depressants that can be applied in the flotation separation of sulphide minerals from serpentine are eager to be developed. Oxalic acid (OA) is a naturally derived organic dicarboxylic acid, which occurs widely in many plants (e.g. spinage, amaranth) (

Effect of a novel phosphate on the flotation of serpentine

May 01, 2020 The test work was carried out in the flotation cells (XFD-63) with 1000 g sample. The cell with the volume of 3.0 L for rougher and 1.0 L for cleaning flotation, respectively, was mechanically agitated, at agitation speed of 1590 rpm. The ore was ground in

A Novel Method to Limit the Adverse Effect of Fine

The rheological properties of flotation pulp were measured in apparent viscosity by control shear rate (0–400 s 1) mode, whereas the shear yield stress was measured by control shear stress (0.02–20 Pa) mode. For each rheology test, 40 mL of slurry sample with a designed concentration was prepared in an agitating flotation cell.
