flocculant dilution effects on flocculation in mineral

Improving flocculation and dewatering performance of iron

In the laboratory flocculation tests the effect of flocculant dosage (5–20 g/t solid), slurry solids concentration (3–12 %), pH (4–12), and flocculant dilution (0.05–1 %) on the performance indicators including settling rate (cm/s), turbidity of supernatant (NTU) and sediment volume (mL) were evaluated.

Thickener Operation and Flocculant Application

This increased dilution showed an immediate and dramatic change in the solids settling rate and dosage requirement (Figure 3). Using massive dilution, greater than 100:1, results in near instantaneous flocculation of solids at the centerwell. An immediate reduction of 25 percent in flocculant dosage was seen.

The effect of flocculant solution transport and addition

While a higher flocculant sparge velocity will generally have a positive effect on feedwell hydrodynamics, care must be taken to minimise the effect of shear on the flocculant solutions during transport to the feedwell, which could potentially lead to increased flocculant demand and inefficient flocculation (i.e. poor overflow clarity).

flocculants and tailings – process productivity

Flocculants and tailings – Process productivity

Let’s consider a few scenarios where flocculant selection can make a difference. 1. Feeds needing high solids dilution prior to flocculation. Fine particle flocculation leads to fractal-like aggregate structures, meaning that when they are large, they are highly porous and fragile. Large, fast-settling sizes often requires solids dilution

salt coagulation or flocculation? in situ zeta potential

Salt coagulation or flocculation? In situ zeta potential

The aggregation state of mineral slurry by coagulant with the presence of clay nanosheets appears similar to a flocculation gel with the absence of flocculant. The interactions between particles in mixed clay and quartz minerals systems are influenced by the interactions of ion correlation and slime coating, which creates zeta potential variation.

Evaluation and optimization of flocculation-sedimentation

The concentration used for flocculation was kept at 60 ppm. At higher polymer dilution, filtration cycles were longer before plugging occurred, and larger flocs formed. At high dilution, the polymer had better contact with coal particles and improved flocculation. With better particle-flocculant contact there was less free polymer in the solution.
