To provide a recycling method for calcium fluoride (CaF2) sludge capable of yielding useful products which solve the problem of pollution and have a high value.

This recycling method for the calcium fluoride sludge includes the following process steps (1) to (4): (1) dry powder is obtained by drying the calcium fluoride sludge in a rotary kiln kept at ≤150°C, then pulverizing and sieving the powder; (2) soil A is obtained by granulating the dry powder, a binder and a mineralizer by dry process agitation mixing; (3) a basic soil material is obtained by subjecting feldspar, kaolin, quartz and clay to dry process agitation mixing then maturing the mixture; and (4) the final product is obtained by subjecting the soil A, the binder, the basic soil material, fired kaolin, pottery stone grains and ceramic pigments to dry process agitation mixing and granulating, sieving then subjecting the particles to high-pressure molding after maturation, followed by high-temperature sintering after drying.
