Is geothermal energy usable to produce salt from sea water?
First why is it necessary to produce salt? Salt is readily available from salt pans (salt drying beds) and requires no energy other than sunlight. Secondly, if geothermal heat is available close to shore installations, then it should be used for desalination of sea water for human consumption with the concomittent production of a slurry of concentrated brine. Energy is energy…no matter what source and can be channeled to whatever purpose needed. It matters not whether power is geothermal, nuclear or fossil-fueled. Your question is simplistic.
