This invention relates to the field of mineral-based solid waste resource recycling, specifically to a solid waste-based homogeneous slurry and its preparation method. Using mineral-based solid waste as the core raw material, supplemented with water, grinding aids, and potential regulators, a stable solid waste-based homogeneous slurry is prepared through a complete process including raw material pretreatment, coarse grinding, fine grinding, graded closed-loop screening, precise Zeta potential control, and ultrasonic homogenization. This slurry can be used with composite solidifying agents to prepare solidified soil for engineering applications. This invention establishes a precise matching mechanism between the calcium content of solid waste and the potential regulator. Potassium hexapolymetaphosphate is preferred for high-calcium mineral-based solid waste, while sodium pyrophosphate is preferred for low-calcium mineral-based solid waste. It is suitable for all types of high-calcium and low-calcium bulk mineral-based solid waste. The prepared slurry exhibits excellent homogeneity and can be stored for a long time. The solidified products have high mechanical strength and low performance dispersion. The preparation process parameters are controllable and suitable for large-scale continuous production, showing broad application prospects.
