Effect of Various Parameters on Dewatering of the Coal Preparation Plant Fine Tailings Using Anionic Flocculants
Abstract :
Solid‐liquid separation is performed in the settling tanks (thickeners) in coal preparation plants. Themain objective of the solid‐liquid separation is to obtain a clear supernatant liquid with a low turbidity to reuse in the plant and a dense‐slurry. It is important to produce good quality recirculation water for the smooth and efficient operation of the plant; or else the presence of suspended solids in the wastewater can lead to a reduction in the efficiency of the process. In this study, settling characteristics of the samples taken from the thickener feed of Dereköy Coal Preparation Plant (Soma, Manisa) were investigated using anionic flocculants. In the settling experiments, the effects of the process parameters including flocculant type, flocculant dosage, suspension pH and temperature on flocculation of the fine tailings of coal preparation operation were determined. Although the settling rate increased at high pHs, more turbid suspensions were obtained.
