Rock salt mining
This is an underground mining process in which the salt is physically dug out of the ground in an operation involving drilling, blasting and crushing the rock. The major percentage of this output is used for winter road maintenance (road ‘gritting’ or ‘salting’).
Solution mining and brine evaporation
This is the most common process for the production of industrial and edible salt in Northern Europe. Water is pumped into the underground rock salt deposits from above the ground to produce fully saturated brine, which is then pumped back to the surface.
Originally, salt was produced by boiling the brine in ‘open pans’, to evaporate off the water, leaving salt crystals. It is now evaporated under vacuum in huge evaporator vessels, to produce the familiar white salt. This salt can be used in industry, in catering and, of course, at the table.
Solar salt production
In hot countries, salt is produced by allowing the sun to evaporate sea water in shallow pools or ‘pans’. Because our mean temperatures are lower and the rainfall higher, there is no commercial solar salt production in the United Kingdom.

In theory, you could make familiar table salt by titrating HCl against NaOH (hydrochloric acid and sodium hydroxide) until the solution exactly balances 7.00 pH. At this point you can evaporate or boil off the fluid and pure sodium chloride (table salt) will remain.
Highly unrecommended as both reagents are highly toxic and if you don't get the process precisely right, you may injure or poison yourself.
