Abstract

In this study, the Box-Wilson statistical experimental design method was employed to evaluate suspension pH, salt (CaCl2 center dot 2H(2)O) concentration and anionic flocculant (A-150) amount in flocculation of coal. Response function coefficients were determined by the regression analysis of experimental data and the predictions were found to be in good agreement with the experimental results. The optimum pH, salt (CaCl2 center dot 2H(2)O) concentration and anionic flocculant (A-150) amount were determined as 9.8, 0.0009 M and 791 g/Mg respectively, when minimum turbidity and maximum settling rate are considered.
