"...The salt is generally stored in the database right next to the hash. In fact, it needs to be. How else could the web server hash the incoming passwords when checking them? So if you have a database dump, you have the salts.
You can often tell by the format or the length of the hash. For instance, a bcrypt hash usually begins with the marker $2b$
