by rivers
Two ways of obtaining salt in the Sahara are through salt mining in salt mines, such as the Teghaza mines in Mali, and through extracting salt from salt flats or panes, where brine is evaporated to leave behind salt deposits.

The salt crystals can be gathered and used in a variety of ways. Personally, I like salt on my fish and chips, here in the UK!
A coarse grained salt, either sea salt or kosher salt is used, though they also sell Margarita Salt which is a corse grained salt and is probably one of those two.
used for a fillter for salt
One way was to dig holes in the ground, pour salt water in it, and evaporating the water, leaving the salt behind. The second way was to mine for them from the salt mine in taghaza
Salt water can be distilled, either by boiling it, or by evaporation in sunlight.
- by the evaporation of water crystallized sodium chloride is obtained - by distillation of water sodium chloride is obtained as a residual product
how are rulers used
There are natural salt deposits that were/are mined. Before this was done salt was collected from sea water. These are the ways still used to obtain salt, but improving salt extraction technologies have made it easier to obtain large quantities.
