| The objective of this study was to investigate the impact of various operational parameters, including aeration rate, feed flow rate, collector and frother dosage, on the efficiency of coal flotation. A pilot-scale column flotation process was utilized. CCD method and ANOVA were used to develop the process model from the input-output data set of a pilot scale column flotation process and to test the weight recovery models and concentrate ash percentage. By optimizing the parameters, such as using a fuel oil collector dosage of 900 g/t, MIBC frother dosage of 340 g/t, and an aeration rate of 10594.6 ml/min, a column flotation operation achieved a recovery of 50.06% and an ash concentrate of 11.6%. The results showed that the aeration rate had the most significant influence on the ash content of concentrate and recovery, compared to the collector and frother dosages. | ||
