In this paper,through the study and analysis,a cyclic unsaturated-saturated state is formed owing to tailing liquid osmosizes tailings sand soil in the course of venting tailing liquid.

Effects of soil amendments on the characters of mixed soil(copper mine tailing and garden soil) and on the growth of ryegrass on it;

To study the water-holding capacities of the artificial soil composed of fly ash, sewage sludge and mine tailing, which was applied to the abandoned rock mining junkyard reclamation, experiments were designed to simulate rainfall and natural evaporation.

The effect of application EDTA as enhanced reagent and applying different voltage drop on the copper electrokinetic processes in a Cu mine tailingswas examined.

Study on reclamation technics of copper from copper milltailings;

Discussion on comprehensive utilization of tailing sand in Jinping phosphate Mine;

Experimental study on dynamic deformation and dynamic strength of tailing sands;

Study on reinforced tailing sand by triaxial compression test;

The geopolymers were synthesized using gold-tailings, metakaolin, water glass, sodium and potassium hydrate.

This paper analysed the practicability of making building materials such as cement,glass,ceramic,brick,tile and so on from the gold-tailings of Sanshan Island.
