This study was performed to investigate the efficiency of hindered-settling column for recovering carbon from Korean anthracite. Laboratory scale hindered-settling equipment was set and two coal samples were prepared for tests. For each samples, washability analyses were performed, and several set of tests were conducted to evaluate the effect of two important operating variables, set point and teeter water flow rate. Also, mathematical model of continuous hindered-settling separation was developed. Modeling program was established and simulations were carried out to evaluate column performance at several operating variables, such as dispersion and teeter water flow rate.
