A lot of waste water and tailings were produced during mineral processing. Polyacrylamide, as an organic polymer flocculant, was widely used in the flocculation treatment of mineral processing wastewater and tailings. In this paper, the types of polyacrylamide commonly used in flocculation of wastewater generated from the beneficiation of metal ore, oil sand and phosphate ore were summarized.

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 ...

Fine particles processing: shear-flocculation and carrier ...
Abstract Shear-flocculation/flotation and carrier flotation are methods by which fine mineral values are aggregated and then recovered by flotation. The aggregates formed have better floatabilities. Without prior treatment ahead of flotation, significant quantities of fines are lost in tailings. An overview of the problems associated with fine particles is presented.

10%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.
