how is table salt obtained?
Answers
Explanation:
While the ocean is a natural salt brine, hydraulic mining (or solution mining) of salt involves pumping water below the earth's surface to dissolve salt deposits and create a salt brine. This brine is then pumped to the surface and evaporated to create salt. ... Most table salt is produced with this method.

Table salt is a refined salt containing about 97-99 percent of sodium chloride. While the ocean is a natural salt brine,hydraulic mining of salt involves pumping water below the earth’s surface to dissolve salt deposits and create a salt brine.the brine is then pumped to the surface and evaporated to create salt.the salty brine may be treated prior to evaporation to reduce mineral content thus yielding a nearly pure sodium crystal.This method is highly inexpensive
