The invention discloses a process for bleaching recovered wax, comprising the following steps of: (1) melting the recovered wax to 180 DEG C by a wax melting pot; and (2) adding activated bleaching earth according to the proportion of 2.5g of the activated bleaching earth to each cubic meter, and standing for 6 hours, wherein the activated bleaching earth plays a role of adsorption to bleach the wax during the 6 hours. In the invention, the recovered wax is melted by the wax melting pot and then a certain amount of the activated bleaching earth is added to the recovered wax, so that impurities in the recovered wax are filtered and the original property of the wax is reduced; therefore, the invention realizes the reutilization of waste wax, prompts the environment protection, saves resources and reduces the production cost.
