Element important, aluminium? Find it in here (8)

I believe the answer is:

tantalum

'element' is the definition.
(tantalum is a kind of element)

'important aluminium? find it in here' is the wordplay.
'find it in here' indicates a hidden word.
'TANTALUM' can be found hidden inside 'important aluminium'.

(Other definitions for tantalum that I've seen before include "Metallic element, symbol Ta" , "Acid-resistant metal" .)

I've seen this clue in The Telegraph.
