A research on strength improvement of clay with mine tailing

Tailings seem to be the materials left over after the separation process of the desirable fraction from the uneconomic fraction of an ore. A vast quantity and diversity of mine tailings are created everyday around the world. The tailings very often contain heavy metals, chemicals and toxic substances that may disperse into the ecosystem and endanger public health during mineral processing. Those mining waste should be managed properly. To assess these problems, it is necessary to ascertain the appropriate engineering properties of the tailings. A series of experimental studies were performed to determine the geotechnical properties of mine tailings to evaluate the applicability of these materials for construction purposes to undertake this project. The specific index and engineering properties of the soil were calculated by various laboratory experiments. Chemical analyzes were carried out, too.
