Then i made a copy of the 12 words mnemonic from the blockchain account.

So my question is: how to get a list of the address corresponding to non zero balance from the seed of a HD wallet?
You mean Blockchain's online wallet?
They use standard derivation paths of BIP44 for legacy and BIP84 for SegWit HD wallets.
Here's Info about the paths:
bip-0044 |
bip-0084And if you even created a second or third "
private key wallet", you'll need to modify the derivation path's account_index accordingly.
