What happened to Taranto's damaged battleships

Were the Italian battleships damaged at Taranto salvaged?

All three were raised or worked on, but only Littorio and Caio Duilio returned to service; Conte di Cavour never did.

Italian crews began salvage work on all three damaged battleships. Littorio and Caio Duilio were eventually repaired and returned to service, although the work took valuable time and resources. Conte di Cavour was raised and reconstruction was attempted, but she never rejoined the fleet and was ultimately scrapped. The answer distinguishes successful physical salvage from a timely restoration of fighting strength.
