The invention relates to a method for recycling aluminum ash, and belongs to the technical field of recycling hazardous waste in the aluminum industry. The recycling processing method of aluminum ash of the present invention comprises: 1) mixing aluminum ash and water to carry out a hydrolysis reaction, and separating the solid and liquid after the reaction to obtain a solid material A; 2) mixing the solid material A with an acid to carry out a leaching reaction, 3) According to the order of copper, iron, aluminum, chromium, manganese, and magnesium, the copper, iron, aluminum, chromium, and manganese elements are respectively precipitated and recovered from the liquid B. , Two or more metal elements in magnesium. The method for recycling aluminum ash of the invention solves the problems of environmental pollution and land waste caused by the accumulation of aluminum ash, and realizes the recovery and utilization of more kinds of valuable metal elements, which is helpful to realize the valuable in aluminum ash. Maximum recovery of ingredients. |
