Smelting Enchantment

Yes, I know the smelting enchantment has been suggested before but here is my own take on the idea.

Because there is a cave update, it only seems fitting that we add another mining mechanic/enchantment.

The enchantment cannot be obtained through the enchanting table, instead you have to find the book itself.

A possible place to hide these books could be in the nether because it is a place of extreme heat.

Another place could be in a new biome underground that is focused on lava lakes, it could have a rare structure that could sometimes spawn in this enchanting book.

This enchantment would work exactly how you think it does, it can smelt any ore when you mine it.

Now heres the catch. The smelting enchantment can only be enchanted onto a netherite pickaxe, this being that netherite is completely fireproof and the pickaxe wouldn't burn due to it being hot.

This would only have 1 level to the enchantment.
