Basic description: In the normal aluminum electrolysis production process, it will produce a large number of carbon residue solid waste, which has been clearly listed as hazardous waste. Electrolytic aluminum carbon residue contain a large number of high-value-added fluoride salts in addition to containing harmful elements, if it can be recycled, it will produce huge economic and social benefits. Wet flotation technology can be used to recover and utilize the cryolite in carbon residue, realizing the harmless treatment and resource utilization of carbon residue hazardous solid waste.

Product overview Technical advantages Functional characteristics

Product Overview: Adopting special flotation technology and special supporting equipment, the cryolite and charcoal powder in the slurry are separated, filtered, dried and returned to the electrolyzer for use, and the charcoal powder can be reused as fuel after harmless treatment. The water used in the system realizes closed-circuit recycling, no acid or alkali is introduced, and no "three wastes" and other hazardous substances are generated. The system has a high degree of automation and control, and the production is continuous and clean, economical and environmentally friendly.


  • Adoption of proprietary flotation technology can effectively realize the flotation separation of cryolite and charcoal powder, and the cryolite product is of high quality, of which the charcoal content can be as low as 1.5% or less, which is at the leading level in China.
  • The whole process has a high degree of automation, which can realize standardized production operation. And it is subject to fewer human interference factors.
  • In recent years, it has undertaken the supply, installation, commissioning and technical output of several carbon residue wet flotation projects in China. It has continuously optimized the related technology and accumulated rich experience in project implementation.

It adopts new type of flotation equipment with high degree of automation, stable and reliable.

Adopting new filter, it is more convenient to operate, higher degree of automation, no need for manual operation, easy maintenance and low failure rate.

The harmless treatment of charcoal powder adopts the treatment process without acid and alkali and oxidizing agent, which eliminates the situation that hazardous chemicals are difficult to purchase, transport, preserve. It also eliminates hazards to the building, equipment, and operators.

According to the energy price to choose the appropriate drying heat source and equipment, greatly reducing operating costs.
