I spoke with Barry Dugan of Horsehead Zinc (formerly Zinc Corporation of America) about zinc recovery from galvanizers dross. He said that adding aluminum to dross is the process used by a few recovery companies. Both floating dross (sheet galvanizing) and some normal galvanizers dross is used.
Aluminum dross, a byproduct of the aluminum melting process, is a mixture of aluminum, its oxides, the oxides of alloying elements and less frequently halogenides, carbides and nitrides. Dross has some good benefits, especially considering tension strength and depending on further conditioning steps can be very useful further on.

Sep 03, 2019· If the return on investment is not higher than the cost it takes to recycle, it is not economically viable. The recovery of dross, as well as postindustrial recycling more generally, continue to show the value of recycling aluminum. However, not all processes used to recover aluminum from dross have the same environmental impact.
Dross is a mass of solid impurities floating on a molten metal or dispersed in the metal, such as in wrought iron. It forms on the surface of lowmeltingpoint metals such as tin, lead, zinc or aluminium or alloys by oxidation of the higher melting point metals such as steel, oxidized impurities melt and float making them easy to pour off.

Nakajima et al. (2007) performed a material flow analysis on aluminum dross in order to achieve the goals of aluminum dross recycling and environmental assessment of new developed technologies. Their analytical results showed that in 2003, about 234,000 tons of aluminum was recovered and about 215,000 tons of residual products were produced.
Zinc bottom dross is a byproduct generated during the hotdip galvanising of steel. The liquid zinc reacts with the steel, thereby generating zinc bottom dross and zinc ashes (zinc skimmings).. The zinc bottom dross an alloy of iron and zinc – is deposited on the bottom of the galvanising bath, and is regularly removed.
