Description of key information

Additional information

Slags, Ferronickel-manufg. is a UVCB substance that is known to consist of a number of metal oxides, and more specifically of iron, silicon, calcium, magnesium, chromium (III) and aluminium, as well as of small quantities of Nickel metal. Ferronickel slags do not contain water sensitive chemical bonds/groups that would suggest the ability to hydrolyse. The main components do not undergo hydrolysis.


The only constituent with water sensitive chemical bonds is elemental sulphur which is partially leached out by water and dissociates forming HS−, HSO4and SO4=the species that predominate in the environment that might be found in nature. This indication is in agreement with the composition of all sulphur-containing minerals. However, the elemental content of sulphur in the ferronickel slag is not significant (maximum 0,6 w/w %)
