FLUXES FOR CASTING ALLOYSCastpics
FLUXES FOR CASTING ALLOYS When you have melted enough bullet alloy to start casting what you want to make the first step is to flux your melt so it is nice and shiny and clean looking. When fluxing a melt make sure that the fumes are ventilated out of the work area by blowing them out a window with a fan or doing it outside.

Soldering Fluxes TypesElectronics Hub
Low-Solids/No-Clean Fluxes Pros This flux type comes with the least activity and chemistry. It was developed to eradicate the need to clean the residue. And it does that precisely because of the low activity. It never reacts once the soldering process is done. Also you don t have to clean as there s no residue left behind.

Degassing molten Aluminium advise needed MetalCasting
TLDR you are mixing up fluxes and degassers but your salt should work as-is to help separate dross from clean metal if you get the aluminum hot enough to melt the salt. Long version The salt mix will act as a flux (not a degasser) that will lower the melting point of the aluminum slightly so it flows easier which will help clean metal

SmeltingWikipedia
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores including silver iron copper and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind.

Flux (metallurgy)Wikipedia
In metallurgy a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent flowing agent or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate potash charcoal coke borax lime lead sulfide and certain minerals containing phosphorus.
