STRONG SALT FLOOR COMPRISING HALITE CRYSTALS MAGNESIUM SULFATE AND POTASSIUM

摘要

A method for the production of a floor for solar evaporation ponds, consisting of: Flooding the raft with concentrated brine with respect to nacl; To subject the brine to evaporation until a layer of nacl containing an important volume percentage of holes filled with entrained brine is deposited on the bottom of the pond; Providing on said floor a brine cover with a composition such that, after a period of contact between the floor and the brine cover, the composition of the entrained brine is such that by cooling it crystallizes hydrated magnesium sulfate from the same; Subject the brine cover to cooling to produce the deposit of hydrated magnesium sulfate in the holes of the floor; Vacate the raft; and Flooding the raft with brine saturated with respect to nacl and more concentrated with respect to mgcl 2 than the brine entrained, thus causing nacl to crystallize from said entrained brine to deposit in said voids.
