Valorisation of waste galvanizing dross: Emphasis on recovery of zinc

Zinc dross is the waste product generated during the hot-dip galvanizing, wherein around 11% of the total zinc is arrested by the dross leading to huge zinc losses. Though, there exist several pyro-metallurgical approaches to recover zinc but these are highly energy and cost intensive process; where hydrometallurgical processes take an …

Dross production increases linearly by four times if the bath temperature changes from 880°F to 810°F (471°C to 432°C). At common temperatures used for galvanizing, dross is made of a mesh of zinc-iron alloy crystals encapsulated by molten zinc. Most dross drops to the bottom of the kettle because it is heavier than molten zinc.
