The invention relates to a graphite solid waste recycling method, which is characterized by comprising the following steps: (1) mechanically scrubbing graphite tailings for 0.2-1 hour; (2) feeding into a high-temperature kiln, and calcining at 650-900 DEG C for 1-3 hours; (3) after calcining, pouring into a cold water pool, then transferring to a flotation machine, adjusting the pH value of the ore pulp to 2-3 by using HCl or H2SO4, adding a collecting agent with the weight of 20-50g / t of the ore pulp, and carrying out reverse flotation operation; (4) drying the flotation tailings, transferring into a reaction kettle, and carrying out acid leaching for 4-8 h at a temperature of 30-80 DEG C; (5) washing with deionized water to be neutral, and drying at 110-150 DEG C for 2-4 hours; (6) after drying, feeding into a high-gradient magnetic separator, and carrying out strong magnetic operation, wherein the magnetic separation intensity is 1T-1.6 T; and (7) grinding the magnetic separation product into a white powder product with the particle size of 400-2500 meshes. According to the invention, the prepared quartz powder with the purity of 99-99.5% is uniform in particle size and stable in property, and can be used as filler to be applied to the industries of plastics, coatings, adhesives, rubber and the like.
