The salt and the password (or its version after key stretching) are concatenated and fed to a cryptographic hash function, and the output hash value is then stored with the salt in a database. The salt does not need to be encrypted, because knowing the salt would not help the attacker.
A large salt value prevents precomputation attacks, including rainbow tables, by ensuring that each user's password is hashed uniquely. This means that two users with the same password will have different password hashes (assuming different salts are used). In order to succeed, an attacker needs to precompute tables for each possible salt value.

Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions.
The additional mineral content is so minimal that it doesn't really change its nutritional value. Himalayan salt is often used as a finishing salt in sauces, marinades, or to enhance dishes.
Unrefined sea salt is minimally processed, retaining trace minerals that might lend color or flavor to the salt. (Refined sea salt, though, has been washed to remove minerals and contaminants, so ...
Sodium chloride, also known as 'edible salt' or 'table salt' [87] (chemical formula NaCl), is the principal source of sodium (Na) in the diet and is used as seasoning and preservative in such commodities as pickled preserves and jerky. For Americans, most sodium chloride comes from processed foods. [88]
