The invention relates to coal gangue solid waste recycling and application, and discloses a green method for manufacturing nanometer carbon polymorphic crystal mixture products from coal gangues. By the aid of the green and low-cost method, residual coal and other relevant components can be released from the coal gangues, other components can be supplemented in nanometer carbon polymorphic crystals such as carbon nanometer fibers, carbon nanometer tubes, carbon nanometer onions, nanometer graphite sheets and nanometer graphene in residual coal to prepare formula products, and application of the formula products used as complex additives to downstream complex production can be developed. The green method has the advantages that the components released from the coal gangues of different mineral resources are totally comprehensively utilized for blending the formula products with the optimal functions for classified downstream application, physical grinding is adopted in production procedures instead of chemical corrosion, mixing blending modes are adopted, and accordingly unnecessary component separation working procedures can be reduced; the downstream application includes cement-based, polymer-based and metal-based complex material production.
