Research on emulsified tyre pyrolysis oil as a coal flotation collector

Yang R., Shen L., Wang H.

Physicochemical Problems of Mineral Processing

Vol. 53, iss. 1

279--287

In this paper the possibility of using the pyrolysis oil derived from waste tyres as a collector in flotation of coal was evaluated. The pyrolysis oil was obtained at the initial and final pyrolysis temperatures of 400 and 700 oC, respectively, and the heat holding time of 30 min. Flotation results indicated that the pyrolysis oil emulsion showed stronger collecting ability than diesel and the concentrate ash content just slightly increased in comparison to flotation in the presence of diesel. The contact angle measurement and immersion microcalorimetry test correlated well with the flotation data. The Fourier Transform Infrared Spectroscopy results demonstrated that diesel and pyrolysis oil emulsion is physically adsorbed on the coal surface.
