Can you disenchant cards you obtain from Blackrock Mountain or Naxxramas?

I was thinking about buying one of the expansion packs and was just wondering if I could DE cards for dust. Still a little new to the game.
Best Answer
Previously you couldn't disenchant cards from Adventures you've bought, but after patch 4.2.0.12051 you can disenchant and craft the ones you've unlocked. This change isn't documented in the Patch notes, but it was confirmed by a Hearthstone staff member as intentional.

What cards are safe to disenchant Hearthstone?
The safest cards to disenchant are bad cards from Classic set, since we had all the time in the world to determine that they're bad. Cards like Gruul or Nat Pagle have never seen competitive play, and so are cards that you can safely get rid of without worrying that they will be playable in the future.Can you still disenchant cards in Hearthstone?
You can disenchant any card you currently have in your collection that you have obtained from card packs. In other words, cards from the Basic set (i.e., the ones you receive via leveling up) can't be disenchanted.Hearthstone: Trump's Opinion on All Naxxramas Cards

Answer 2
"Soulbound" cards cannot be crafted; this includes non-golden cards from Naxxramas and Blackrock. Here is a table:
| | Non-Golden | Golden |
| ---------------------- | ----------------------------------- | ------------------------------------------------ |
| Basic Set | Soulbound (obtain automatically) | Soulbound (obtain by leveling up) |
| Classic (Expert) / GvG | Craftable (or obtain in a pack) | Craftable (or obtain in a pack) |
| Naxxramus / Blackrock | Soulbound (obtain in the adventure) | Craftable (once you have the non-golden version) |
| Promotional | Craftable (in some cases) | Soulbound (obtain as promotion) |
| Reward | Soulbound (obtain as reward) | Soulbound (obtain as reward) |
I have confirmed most of the above in the game, except for some of the details on promotional cards.
To craft a golden Naxxramas or Blackrock card, you go to crafting mode and click on "Show Only Golden Cards". This won't work for cards you don't already own. However, you don't need the non-golden versions of classic or GvG cards to craft the golden ones.
