Lead Harris/Parkes Refining Dross Recovery. Refining dross is the result of lead refining process where impurities like copper, tellurium, arsenic-antimony-tin, silver, zinc and bismuth in sequence from lead bullion. Composition of each type of dross varies and is subjected to specific refining steps and raw material contents.

Aluminum Dross Crushing
A method for recovering reusable materials from aluminum dross is disclosed comprising crushing the dross and extracting solubles therefrom with water in a digester. The brine so obtained is processed in a crystallizer to obtain fluxing materials contained therein, and the insolubles are furnaced to separate the free aluminum metal therefrom.

resulting from dross crushing
Metallic aluminum in aluminum dross is recovered in Japan generally by physical separation, using the so-called Metal Reclamate Machine (MRM). A large amount of the residue containing oxides, metallic aluminum, nitrides and salts is unavoidably generated as a by-product of the MRM process. Since the metallic aluminum is much more viscous than the relatively brittle oxides and nitrides, it
