EXPERIMENT FOR THE UTILIZATION OF TAILINGS FROM BASALT STONE MINE

This experiment puts forward a re-utilization method for the mining wastes (crushed stone and tailings). Based on the thermosetting principle of epoxy organic adhesive, the epoxy resin emulsion, organic curing agent and inorganic adhesives are adopted in the experiment. The composite material is trial produced from the waste basaltic stone with the process of material mixing, molding, pressing, drying, polishing, cutting and dressing. By testing, the flexural strength of the composite sample surpasses that of natural products. Other physical property indexes also reach the corresponding quality standards for building materials. Such re-utilization of the mining wastes is a significance to reduce the tailings of mine, control the environmental pollution and add the benefits of enterprises.
