An electrolytic
aluminum anode waste separating and recovering method relates to the field of
waste recovery and utilization. The method comprises the following steps: a, screening and classification are performed on waste materials; b, materials of which F is greater than F1 are divided into carbon objects and
amorphous carbon objects through manual separation, and the separation of a color sorting
machine or an optical separator; c, magnetic objects and nonmagnetic objects are separated during material conveying; d, carbon is extracted through respective electric separation equipment from the material of which the F is less than or equal to F3 and is less than or equal to F2 after screening and classifying; e, a material of which the F is less than the F3, and other
amorphous carbon materials separated out from other links can be separated into carbon and
amorphous carbon materials through crushing and flotation; f, the amorphous carbon materials in e is added with
fluorine and chlorhydric acid for reaction so as to obtain
cryolite; and g, purer
cryolite is obtained after separation, water scrubbing,
dewatering and
drying. The invention has the benefits as follows: various
material separation and purification from waste can be accomplished by using a series of processes such as optical separation, color selection, manual separation,
magnetic separation, electric separation, floatation,
chemical reaction and the like, so as to meet the requirements of industrial application. The separation cost during the entire process is low, the demand for labor force is low, and industrial
automation continuous production is achieved.
