  • Aluminum recovery from dross by flotation ScienceDirect

    Batch flotation tests using drosses activated with copper were carried out in a Wemco Laboratory cell. Aluminum was easily floated yielding concentrates assaying up to 80% aluminum with recoveries higher than 70016. Flotation kinetics was fast and selectivity high so that no cleaning was necessary to obtain a concentrate.
