In this paper, a process for solid-liquid separation was investigated by thickening method on the slurry obtained from leaching process under optimum conditions (Saghand Anomaly 1 soil). In mineral processing industries, the correct selection of the type and amount of flocculant can reduce the diameter of thickener, leading to an increase in the efficiency of the separation process and reducing the costs. Thus, in the present work, the experimental thickening was carried out by varying the amount of flocculant K-300 for solid-liquid separation process. By comparing the sedimentation rate of each experiment, the optimal value of flocculant for solid-liquid separation process (Saghand Anomaly 1 soil) was 80 g/tonore.
