  • Aluminium recycling and environmental issues of salt slag

    Aluminium recycling and environmental issues of salt slag

    Recycling the scraps with lower recyclability normally generates more salt slags. High slag viscosity leads to more fine aluminum metal entrapped in the salt slag and thus increases the load of salt slag recycling. It was found that viscosity of the salt flux is increased with the amount of entrapped nonmetallic components, which affect the ...
