  Application of acid mine drainage for coagulation/flocculation …

  201561 · Abstract. A novel application of acid mine drainage (AMD) for biomass recovery of two morphologically different microalgae species with respect to AMD dosage, microalgal cell density and pH of medium was investigated. Optimal flocculation of Scenedesmus obliquus and Chlorella vulgaris occurred with 10% dosage of AMD at an …

  Processes | Free Full-Text | Efficiency of Coagulation/Flocculation …

  Coagulation and flocculation treatment of laundry wastewater required higher dosages of coagulants compared to synthetic matrix and surface water due to the presence of surfactants in the water ( Table 1 ). Lower dosages were also investigated, but since no precipitation occurred, the results are not presented.

  Data-driven modelling of the flocculation process on mineral …

  2018920 · Abstract The clarification of tailings slurry using polymer flocculants has been widely used in the mining industry to promote the cleaner production of mineral resources. In this paper, a data-driven prediction model was proposed using gradient boosting machine (GBM) for the non-linear relationship modelling and firefly algorithm …

  Flocculation, dewatering and sedimentation behaviour of mine …

  202441 · To improve the filling efficiency and ensure mining safety, these stable thickening underflow, flocculation mechanism, dewatering behaviour, and its regulatory methods brought about by this complex deep cone thickener (DCT) are the central issue that this paper needs to focus on the reviewing, exploring and understanding.

  Wastewater treatment using plant-derived bioflocculants: …

  There has been a surge in interest in the coagulation–flocculation method for wastewater treatment. Polymer bridging, electrostatic patching, and charge neutralization are all common flocculation mechanisms. As shown in Figure 2, polymer bridging is the most widely accepted mechanism for plant-based bio-flocculation.

  A method for estimating the flocculation time of …

  1998111 · A new method is presented for determining the flocculation time of monodispersed sediment suspensions. Flocculation time is the critical time at which abrupt changes in the particle size spectrum of an aggregative suspension occurs. This method predicts flocculation times to within 6% of values predicted by a geometric sectional …

  Calcium Chloride Applications for the Mining Industry

  Four unique properties Four properties of calcium chloride make this basic chemical compound a versatile material for the mining industry. The first three properties all relate to calcium chloride’s constant urge to return, or remain, in its natural liquid state.

  Optimizing the addition of flocculants for recycling mineral-processing ...

  20151027 · Mineral processing requires large volumes of water, but water is limited at mining sites. Therefore, techniques to recycle mineral-processing wastewater without negative effects on recovery and flotation grade are critical. Among a number of technologies to recycle water, flocculation using an anionic polymer was tested for …
