- Sainmhíniú mixture generated when melting light metals (aluminium, magnesium) using salt mixtures (salt fluxes) to cover the molten metal so as to prevent oxidation and to increase thermal efficiency and yield (by facilitating the breakdown of prior oxide layers on the surface of the scrap to be melted and and thence promoting improved separation between the metal and its non-metallic contaminant) Tagairt "COM-Terminology Coordination, based on:European Commission. JRC. Best Available Techniques (BAT) Reference Document for the Non-Ferrous Metals Industries, http://eippcb.jrc.ec.europa.eu/reference/BREF/NFM_Final_Draft_10_2014.pdf [10.12.2015] & RVA.

- Nóta These slags are generally produced in rotary furnaces and have an adverse environmental impact if they are deposited on land. The quantity of salt slag produced varies considerably and is dependent on the type of material, the furnace and the degree of contamination, etc. There are options available for salt-free melting in some furnaces using many types of feed materials and there are options for recycling all of the components of salt slag.Salt slag can be completely recovered to produce marketable products without producing any residues except for some activated carbon (if used at all). Two types of recovery processes exist: the full recycling process and the partial recycling process. In the full recycling process, all the components in salt slag are completely recovered and there is no generation of waste water.

- Nóta "Les déchets de l'aluminium, crasses blanches et crasses noires, eux-mêmes traités traditionnellement avec ajout de sels, donnent lieu à un résidu, le laitier. La mise en décharge de ce dernier n'étant plus autorisée, deux options sont possibles : le traitement du laitier, ou le traitement des crasses sans ajout de sels. http://www.ree.see.asso.fr/IMG/pdf/0141fb9354/pdf03/1995_0003_06.pdf [mai 2016]"
