With the continuous progress of industrial technology and the enhancement of ecological environment protection, the mine filling technology not only meets the requirement of high-efficiency mining of mineral resources to the maximum extent, but also can cooperatively treat mining and smelting wastes such as tailings, waste rocks, smelting waste values and the like. On one hand, the mining and metallurgy solid waste can be used as filling aggregate for filling the goaf, and on the other hand, the mining and metallurgy waste residue with potential gelling activity can be used for preparing a novel composite filling gelling material to replace cement.
The boron mud is waste residue discharged after borax is industrially produced by using boron magnesium (iron) ore, and about 4-5 tons of boron mud is discharged when one ton of borax is produced. At present, borax production plants in China are more, a large amount of boron mud is discharged and accumulated in the field every year, land is occupied, and the environment is polluted. The boron mud is a mixture of various inorganic compounds, and contains a certain amount of B2O3The content of MgO is also high and a considerable amount of SiO is contained2And small amount of CaO, FeO and Al2O3And so on.
