 — In terms of production volume, aluminium is the leading metal in non-ferrous metallurgy. In particular, the recycling of aluminium-containing residues has strongly increased in recent years and will continue to gain importance in the future. Due to the high affinity of aluminium to oxygen, the oxidation of the molten bath is unavoidable, which …

 — This article will focus on the causations of melt loss and dross generation based on two melting process types: a side well melting furnace (which has a side well …

refining capacity. In addition to drossing, BEP requires partial PR to control certain impurities (antimony, arsenic, and bismuth) to levels necessary to maintain anode integrity and slime adherence during electrorefining. Thus, rough drossing and some softening of the bullion is required prior to electrorefining. One BEP operation

 — Drossing fluxes promote separation of molten aluminum entrapped in the dross (sometimes up to 80%). Besides chlorides and fluorides drossing fluxes contain oxidizing component (KNO 3) reacting exothermically with aluminum when heated.Heat generated by drossing flux improves wettability and fluidity of the entrapped aluminum, …

Overexposure to lead is a leading cause of workplace illness in the lead industry. Employees working in secondary lead smelter plants are exposed to one of the highest lead exposure levels among all lead-related industries. Smelting is the process of reducing reclaimed lead compounds to elemental lead.

 — In-plant aluminum dross recovery has been available for some time, but isn't widely used for small volumes of dross. Crucible melting furnaces typically generate 5-25 lb of dross, and most recovery equipment has been considered too cumbersome to move from furnace to furnace.

 — Koltun et al. (2010) undertook an LCA study of aluminium smelter cast house operations in Australia, which are a small fraction of the impacts associated with the smelting process, but are still ...

Molten, refined, or alloyed lead is pumped via heated pipes from kettles to a casting reservoir, or casting wheel, which directs a measured amount of lead into steel or cast iron molds. Hand operations include drossing and stacking cooled castings. Castings typically consist of "pigs" (up to 80 pounds) and blocks (up to 2000 pounds) (Fig. 1 ...

Explore the properties, formation, and treatment of dross, a by-product of aluminum melting processes. Learn about the factors influencing its volume and metal content, and the modern processes for its conditioning.

 — Drossing fluxes. It is known, that a large percentage of usable metal may be lost, when the "wet" dross is discharged from the furnace. Wet dross contains 60-80 % of metal. Many industries are trying to reduce the metal content in such dross by treating the dross in a furnace using exothermic fluxes.

Use a drossing shovel, which allows molten lead to drain prior to removal of dross. Use local exhaust ventilation at drossing access locations. Eliminate or minimize the use of a …
