Physical and Mechanical Properties of Aluminum Dross
The study on the physio-mechanical behavior of aluminum dross has been carried out. The amount of aluminum dross used varied between 50 and 90 wt %, while bentonite added to the dross varied from 10-50 wt % with a fixed amount of water. Using dross particle sizes of 106 µm and 184 µm, 10 samples are produced from each particle size.

Dross or Slag
Dross is a byproduct of metal (sometimes a useful raw product) and is therefore sometimes the result of smelting, sometimes refining. Two more things add to the confusion. Dross can be heavier than the metal being processed (especially in the case of aluminum), and the type that is useless is also destined for the slag heap.
Dross Inclusions
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.
