Embodiment Construction
[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0015] The invention provides a technical solution: a processing method for recovering aluminum ash, comprising the following steps:
[0016] Aluminum ash is ground and cast to obtain aluminum blocks;
[0017] Dissolve the aluminum block in water to form a mixture and ammonia;
[0018] Add sulfuric acid to the mixture, adjust the pH to 7, then add 15%-20% cement, and granulate it into sand.
[0019] The specific steps for aluminum ash to be ground and cast to obtain aluminum blocks are as follows: first, the automatic feeding machine sends the aluminum ash into the silo, and the electromagnetic vibrating feeder at the bottom of the silo evenly sends the aluminum ash into the ball mill for further processing. Grinding, the ground aluminum ash is ...

The invention provides a processing method for recovered aluminum ash. The processing method comprises the following steps of grinding and casting aluminum ash to obtain an aluminum block; dissolvingthe aluminum block into water to form a mixture and ammonia water; and adding sulfuric acid in the mixture, adjusting a pH value to be 7, then adding 15-20 percent of cement, and performing granulation to prepare sands. Compared with the prior art, the processing method has the beneficial effects that aluminum can be better separated from the aluminum ash, so that the recovery rate of the aluminumin the aluminum ash is greatly increased, energy consumption and waste are lowered, and the cost is reduced; the method is harmless to environment, is high in utilization efficiency, is simple in technological process and low in investment and cost and environmentally friendly in the whole utilization production flow as well as facilitates large-scale popularization and application; and the formed aluminum, ammonia water, aluminum sulfate and sands can be reused, and a harmless and pollution-free result is basically realized.
Description
technical field [0001] The invention relates to a processing method for recovering aluminum ash, which belongs to the field of aluminum ash recovery methods. Background technique [0002] Aluminum ash (aluminum ash / aluminum slag) is a common waste in the aluminum industry with a huge output. Its main source is the infusible inclusions, oxides, and additives floating on the surface of the aluminum melt during the smelting of aluminum and the production of aluminum alloys. And the reaction products produced by physical and chemical reactions with additives, etc., are produced in all production processes where aluminum is melted. [0003] The amount of aluminum ash produced by aluminum factories is very large. A large aluminum rod factory will produce thousands of tons of aluminum ash a year. If the aluminum ash is not handled properly, it will bring great harm. [0004] At the same time, aluminum ash, as an important secondary resource of aluminum, has attracted more and mor...
