Description 103-110
This work presents the flotation of a sub-bituminous coal using 1-butylamine as a short-chain amine collector. The
flotation results have been obtained with 1-butylamine (coal yield: 100%) and compared with those achieved with a
quaternary amine (coal yield: 95.4%), kerosene (coal yield: 100%) and diesel (coal yield: 95.7%). The best results have been
obtained with 1-butylamine. Less depressant effect has been observed with 1-butylamine. The FTIR signals have been
attenuated when the coal is conditioned with 1-butylamine. Zeta potential measurements have also been changed after
conditioning. The contact angle of water and graphite has decreased from 82.3° to 32.2°. An optimization has been
performed using a Box-Behnken experimental design. Flotation has significantly affected by time and collector dosage. The
pH is not a significant factor. The optimal conditions for the best efficiency using 1-butylamine as a collector are 2.0 min of
flotation and 10-3 mol/L of collector.
