Abstract:

A newly developed coal flotation collector EDO and its flotation characteristics for three Shanxi different coals were introduced in this paper. EDO was an emulsion composed by diesel oil, water and independent development surfactant PGS. Compared flotation experiments show that, at the same dosage, EDO gives 2~5% combustile material recovery promotion than typical collector with only a slightly ash content increment, but saving over 70% diesel oil, and improves the floatation speed. EDO could promote the dispersion of diesel oil in the slurry, so that the efficiency of floatation was improved. The flotation results showed that the EDO had the characteristics of excellent performance, high selectivity and good stability.
