How to Improve the Thickening Effect of Thickener?-xinhai

01 1. Use flocculant to improve concentration effect. The size of grains in pulp is different, and the settling speed of materials in water is related to their particle size, the finer the particle size is, the slower the settling speed is, and some processes require relatively fine grinding particle size to achieve better separation index, therefore, how to make the effective settling of fine

Most common problems in thickener operations (part 1)

Thickener area. The thickener area depends on the mineral sedimentation rate (m2/t/d) or the specific feed rate (t/h/m2) which are determined by laboratory or pilot testing. These tests are carried out with representative samples of mineral and different granulometry. The tests also evaluate different dosages of flocculant.

The Effect of Solids Concentration, Flocculant Dosage and

the presence of 10 g/t flocculant, settling fluxes was obtained in the range of 0.38 and 9.7 t/m 2h for the size fractions of +44-63 and +125 μm respectively. It could be suggested that, with certain flocculant dosage, setting flux and thickener capacity were reduced with particle size. Furthermore, settling flux

Thickener Operating pH and Lime for Flocculation

Settling: Without VS With Flocculant If, for some reason, the thickener's settling rate is too slow, as in the case of the grind being so fine or you are dealing with clay rich ore and now the concentrate stays in suspension. The thickener could be "sliming"

Thickening Resource Book

Thickening Definition Continuous thickening by an operation called sedimentation is the separation of suspended solid particles from a liquid stream by gravity settling. The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants.

Number-sensitive particle size measurements for monitoring

Jan 01, 2020· The processing of fine grain, low grade ore bodies favours the application of fine grinding technology to liberate valuable minerals for improved recovery (e.g. from flotation or leaching). However, this can then result in fine tailings that affects water recovery from thickeners through increased flocculant dosages, reduced settling fluxes and
