Hair and metallic mineral stink (6)
I believe the answer is:
furore
'stink' is the definition.
(both can mean a fuss or controversy)
'hair and metallic mineral' is the wordplay.
'hair' becomes 'fur' (fur is a kind of hair).
'and' says to put letters next to each other.
'metallic mineral' becomes 'ore' (rock containing metal).
'fur'+'ore'='FURORE'
(Other definitions for furore that I've seen before include "Frenzied excitement, uproar" , "A general uproar or noisy scene" , "Frenzy, uproar" , "To-do" , "Turmoil, uproar" .)
