What are two ways of obtaining salt in the Sahara desert?

1) Rock Salt Mining: This involves extracting salt from underground salt deposits found in the Sahara. Workers manually dig into the salt beds, break the salt into smaller pieces, and then transport it to the surface. This method has been practiced for centuries and is still prevalent today in some areas.

2) Salt Evaporation from Salt Flats: Another way of obtaining salt in the Sahara is through the evaporation of water from salt flats. During the rainy season, water accumulates in low-lying areas creating temporary lakes. As the water evaporates under intense heat, it leaves behind a layer of salt on the surface. Local people collect this salt, often by scraping it from the surface.
