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.

also provides opportunities to incorporate fluxing agents into the mix to make their use more efficient and to reintroduce mill scale (the iron oxide waste produced during rolling). The sintering machine can take ore as coarse as 10mm and as fine as "all passing through 100 mesh," provided that efficient air flow through the bed is maintained.
