coagulation in mineral processing

  • Mineral processing Wikipedia

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

    Dispersion, selective coagulation and flocculation are the major accessories of the mineral engineering field. The organic and inorganic chemicals used in these functions belong to a group of modifiers. A number of chemicals used as dispersants are also used as depressants and activators. The

  • 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.

    Coagulation and floculation describe the chemical process of contact and adhesion whereby the particles of a dispersion (colloids) form larger-size cluster (flocs or flakes) allowing them to be more easely removed from water (e.g. by settling). The coagulation-flocculation processes facilitate the removal of suspended and colloidal particles.
