Aluminum Dross Processing Recycling and Recovery ALTEK
Ensuring nothing goes to waste. Dross can amount to 5% of a facilities total production, so preserving metal units is vital. Partner with ALTEK to maximize the revenue from your dross. We can reduce dross levels before it leaves the furnace and ensure that metal unit recovery is maximized at each stage of the recycling process.The common processing technique for aluminum black slag in aluminum smelting is grinding and sieving the dross to recover metallic aluminum, and immersing the residual aluminum dross in water at aReview of aluminum dross processing ResearchGate
