Black Salt is widely known as an all encompassing protective salt that can be used for various different things--protection spells, banishing, breaking hexes. And in the reverse--to lay down hexes and curses. It can be sprinkled under pillows to ward off bad dreams, stored in jars or boxes to get rid of unwanted guests or spirits, cast a line across your door or window to barrier negative energies away, use in floor washes/door washes/cleansing ritual area, add into the bath whenever you feel depressed/angry/upset, keep it on your person to ward off gossip/bad influences/negativity, use it as an offering for Underworld deities/dark goddesses, as an offering to fire elementals/ancestors, use for any Dark Moon ritual, add in protected cases that contain your Scrying tools...you get the picture. It's a very powerful tool to add into your witchy cabinet.
Remember: Black Salt absorbs negativity. So, if you use this as a protective barrier--sweep it into the dirt to ground it, wash it away or cleanse the area free of it.
