improving flocculation performance of copper flotation

Improving Flocculation Performance of Copper Flotation

The following results were obtained from jar testing used several types of traditional flocculants (anionic, cationic, and nonionic) and the new generation technology UMA flocculant: In Jar tests, it was observed that all polymers performed well in terms of turbidity on copper tailings flocculation, and the optimum flocculant dosage was 20 g/t.

7. Optimum flocculant concentration. 8. Optimum pulp density. 9. Approximate location of the point of addition. Flocculant testing should be initiated for economic or performance reasons. Also, the product currently in use could become unavail- able, ore may change, or plant conditions may necessitate a new flocculant.

a role of flocculant chain flexibility in flocculation

A role of flocculant chain flexibility in flocculation

Due to the presence of very small residual anionic charges in the nonionic flocculant (N100), its pH increased only slightly compared to that of distilled water (pH 5.3) that was used to prepare the solutions. A much larger increase in pH can be observed for the more anionic flocculants, hydrolysis of which releases higher amounts of OH-. As

Mineral Processing Flocculant

This polymer is called anionic flocculant. If the part carrying positive charge remains on the group (e.g., ( - {mathrm {NH}}_3^ {+} ), ( - {mathrm {NH}}_2^ {+}- ) is generated) and the entire molecule becomes a very large positive ion, the polymer is called cationic flocculant.

1. Introduction. Dewatering is an essential part of mining and mineral processing operations (Dash et al., 2011).Although filtration and centrifugation are commonly used for solid-liquid separation, gravity thickening usually represents the most practical option to achieve high throughput with a desirable performance (Witham et al., 2012).

Evaluation of Anionic and Cationic Pulp-Based Flocculants

In wastewater treatment, flocculation is a widely used solid/liquid separation technique, which typically employs a charged polymer, a polyelectrolyte (PEL). Polyelectrolytes features, such as charge type, charge density and molecular weight, are essential parameters affecting the mechanism of flocculation and subsequent floc sedimentation. The effectiveness of the process is also influenced
