This paper introduced a newly developed coal flotation collector ZFC and its flotation characteristics for Shanxi three different coal samples. ZFC was an emulsion composed by 27% diesel oil, 70% water and 3% homemade surfactant PGS. The surfactant PGS was synthesized with environmental friendly reproducible oil and several surfactants. The flotation results showed that the ZFC had the characteristics of excellent performance, high selectivity and good stability. ZFC could promote the dispersion of diesel oil in the slurry, so that the efficiency of floatation was improved and about 70% diesel oil was saved.
