Study of basic characteristics of full tailings filling material

All tailings filling technology that take full use of tailings for filling the whole aggregate has been widely used at home and abroad, which can not only take the advantages of increased ore recovery, but also reduce the emission of pollutants and protect the environment. In this paper, based on the background of Jinshandian iron mine, mainly through the experimental grain size analysis, sedimentation test, slump test, the viscosity test, uniaxial compressive strength test and scanning electron microscopy, the nature of the whole tailings, flow properties of filling cement slurry and the compressive strength of various cement tailings specimen were tested and analyzed. The optimal mix of all tailings filling material of Jinshandian Iron mine is confirmed which provides a reliable basis to the smooth implementation of cemented filling technology in Jinshandian iron mine.
