Title:
METHOD FOR TREATING ALUMINUM DROSS PARTICLE, AND METHOD FOR PRODUCING ALUMINA PARTICLE
Document Type and Number:
Japanese Patent JP2023150403
Kind Code:
A
Abstract:
To provide an Al dross treatment technique that substantially inhibits the generation of ammonia gas from the treated Al dross and enables recycling of it.SOLUTION: Al dross particles (100) are brought into contact with water in an aqueous medium at 75-95°C, to decompose aluminum nitride in the particles.
