Resource Recovery Solutions For Aluminium Dross Processing

Harsco has developed a cost-effective closed-loop process to achieve an environmentally controlled solution that meets the requirements of environmental protection authorities.

The features of aluminium dross processing are:

• Receipt of dross at processing plant (weighing and storage)
• Loading dross into furnace - Addition of salt flux
• Removal and recovery of aluminium at all stages
• Additional Crushing and milling to recover aluminium from salt cake
• Recycling of non-metallic fractions
• Recycling of salt flux back into production

Our advantages are:

• Maximized aluminium yield
• Re-sale of non-metallic fractions
• Minimised gas emissions (ammonia)
• Environmentally-controlled solution
• Closed loop zero waste process
