  • Uses Of Flocculation For Mining

    Flocculation has found extensive use in the wastewater and biotechnology industries to aid in separation techniques, such as filtration, flotation A chelating flocculant, such as PAMG, was found to readily flocculate copper minerals from the gangue, including calcite, quartz, feldspar and dolomite in the presence of polyphosphates and/or

  • Flocculation Theory and Background

    Flocculation requires gentle mixing and the use of a high molecular weight polymeric flocculant. The flocculant adsorbs to the submicron flocs and facilitates bridging of gaps between flocs (2a). Bringing particles closer together creates the effective range for Van Der Waals attraction forces to reduce the energy barrier for flocculation and

  • Flocculants ArrMaz

    Flocculants are used in the mining industry to treat the water used in mineral extraction and flotation processes. They help aggregate fine suspended particles to form larger flocs so that the solids can more easily be separated from the water. Flocculants are used to clean flotation process water to reduce reagent consumption and improve recovery.

  • anionic flocculant used for Tailings flocculation,China

    anionic flocculant used for Tailings flocculation . Mining processes produce large quantities of fines as waste that need to be handled for the continuity of the operation. The most common treatment route is to thicken the material prior to disposal, shrinking the volume required for tailings storage and allowing water recovery and reuse in the process.

  • Flocculation an overview ScienceDirect Topics

    Selective flocculation of iron ores has already been applied to commercial use [39]. In this case, selective flocculation of iron oxides is achieved using starch and is separated from fine silica using a thickener, and caustic soda at pH 10.5 is used as silica dispersant. • Selective flocculation of

    What is Coagulation and Flocculation? Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.

  • Studies on flocculation of fine mineral tailings using

    minerals and during these processes tailings generated as waste products. For increasing the recovery of valuable minerals, water and small amount of chemical materials and reagents are used during this process. Extracting minerals from primary ores depends on mineral types, but there are some steps which are common in the process.

    In the Chilean mining context, there is a specific need to address the combined effect of salts and typical minerals present in local copper tailings on the flocculation stage. Such minerals include quartz and andesite as coarse fractions and kaolinite, illite, muscovite and/or chlorite (e.g., References [16,17]) as

  • The Use Of Starches And Starch Derivatives As Depressants

    The flocculation of magnetite-taconite tailings depended mainly on the level of starch, whereas their clarification depended on the level of lime. As previously reported in the literature, selective flocculation and partial upgrading of a semi-taconite could be readily attained with starch and calcium chloride.

  • Use Sodium Silicate as Dispersant in Selective Flocculation

    Selective Flocculation Tests. A Ca++ addition of 10 ppm was chosen because flocculation tests, on quartz showed that considerably higher amounts of sodium silicate, involving higher ionic strength and the presence of colloidal silicate complexes, would be required to disperse quartz suspension containing more than 10 ppm Ca++.

  • Effect of pH on the flocculation behaviors of kaolin using

    Solid–liquid separations are employed to many stages of mineral processing, ranging from product liquor recovery to tailings processing. For most tailings and wastes, the main constituents are fine clays, especially for kaolin (Sabah & Cengiz 2004; Masliyah et al. 2011).Flocculation of fine clays is highly desirable and also remains challenging in particles settlement and dewatering ().
