Description

Technical Field

The tailings are currently generally converted into glassy water-quenched slag through water quenching, and the residual heavy metals are sealed in the glass. The slag is then used in building materials such as construction aggregates and cement additives, or is landfilled. The resource utilization value is relatively low. The tailings are composed of SiO2, Fe2O3, CaO, Al2O3, MgO, and small amounts of residual metals. The composition is similar to that of rock wool in mineral wool, and it can replace natural raw materials such as basalt in rock wool production.
