Flocculation Test Procedure Mineral Processing & Metallurgy

A Flocculation Test Procedure is used to determine how much Flocculants need be added to solids in suspension (slurry or pulp) to cause the individual particles to collect in the form of flocs. The formation of flocs aids in improved settling rates, better overhead clarity and/or faster filtration rates. There are three main methods for achieving aggregation of very small or colloidal

Flocculation in Mineral Processing SpringerLink

Abstract. Flocculation is a characteristic property of colloidal dispersions. The typical classical sol contained sub-microscopic dispersed particles which would pass freely through ordinary filter-paper, and were too small to be resolved by any transmission optical microscope. Consequently, an arbitrary size limit of 0.1 μm could be defined as the upper size boundary of the colloidal range.

Chapter 11: Dispersion, Coagulation and Flocculation

The action of dispersing agents in mineral processing is therefore to (a) improve flotability of the mineral by preventing slime coating on the mineral particles and (b) disperse fines or gangue minerals during selective flocculation. The flocculation process is opposite to dispersion.

Coagulation an overview ScienceDirect Topics

Coagulation by electrostatic attraction occurs when two particle types have opposite charge and there is mutual attraction. An example of silica and iron oxide minerals was discussed in Chapter 12.Talc presents an example of a single mineral subject to electrostatic coagulation, as the charge on the basal plane (face) is usually negative and the charge on the edge (at least below about pH 10

When used in conjunction with a mineral coagulant, the anionic flocculant tends to be the best option. When the only requirement is the removal of suspended solids, a synthetic flocculant can be used on its own. sludge dewatering. Cationic flocculants are usually suitable for organic sludge processing. Mineral type sludge requires anionic

Mineral Processing and Extractive Metallurgy Review

Physical characteristics of mineral aggregates (such as density, size, shape, structure and strength) formed by either electrolytic coagulation or polymeric flocculation, need to be critically controlled by optimum conditioning in mineral processing. The present stone discusses the various experimental techniques used to determine these properties.

Coagulation-Flocculation SSWM Find tools for

Coagulation-flocculation is a stone water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles. Coagulation is a process used to neutralise charges and form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter.

A process of selectively agglomerating coal in an aqueous environment while leaving the mineral matter dispersed has been developed. This process is autogenous for hydrophobic particles in that neither an agglomerating agent nor an electrolytic coagulant is needed. It is based on the finding that hydrophobic particles are pushed against each other by the surrounding water structure.
