ABSTRACT Large tonnages of chromite tailing were discarded during processing of chromite ore in the
conventional circuit. A typical chromite plant tailing was treated in wilfley table for the recovery
of chromite values. Optimisation study was carried out for the process parameters of wilfley
table using empirical models, developed from the experimental data. It was found that grade and
recovery (% Cr2O3) in the concentrate fraction majorly depended on the variation of deck tilt
angle. To achieve high grade (>45%) with acceptable recovery (>40%), set of optimisation
condition of parameters have derived which resulted large quantity of wash water (>5lpm of
flow rate) is necessary. Validation of the empirical models were done with set of tests which
resulted good agreement with the predict values (R2 is 0.96 and 0.99 for the grade and recovery
