Aluminum ash is the slag produced in the production process of electrolytic aluminum or cast aluminum, which is a hazardous solid waste. Aluminum ash contains aluminum element, aluminum oxide, aluminum carbide, silicon, fluoride, chloride and other components. Among them, alumina accounts for more than 70%, which has a high recycling value. Aluminum ash is divided into primary aluminum ash, secondary aluminum ash, cathode carbon block, anode carbon slag, electrolytic cell impermeable material, refractory, aluminum alloy factory dust collection, aluminum processing sludge, etc.

We supply complete aluminum ash treatment plant equipments with the whole service of design, manufacturing, installation and training. Please contact with us to get quotation and best solution!


Aluminium ash should start from the potential value of quantity, nature, composition, etc., and the directions of use are as follows:
1. The aluminum ash ball mill production line of Henan Zhengzhou Mining Machinery Co., Ltd. can effectively extract the elemental aluminum in the aluminum ash, which can be used for smelting aluminum ingots.
2. The waste ash after aluminum extraction with the aluminum ash ball mill production line of Henan Zhengzhou Mining Machinery Co., Ltd. can be directly used to produce special cement.
3. The aluminum ash mixing mill and aluminum ash rotary kiln production line of Henan Zhengzhou Mining Machinery Co., Ltd. can produce calcium aluminate and water purification materials.


Harmless aluminum ash hazardous waste disposal program: through acid leaching, alkaline leaching, washing, etc., the nitride, fluoride, salt and other impurities in the secondary aluminum ash are removed to obtain harmless aluminum ash before safe filling Buried. 
Recycling process: After removing toxic and harmful substances, the secondary aluminum ash is processed by high temperature or cold processing to produce different products such as steel claw protection ring, brown corundum abrasive, refining agent and water purifying agent, etc., or return to the electrolytic cell as electrolytic aluminum raw material.
