Brief description of a salt, in particular potassium chloride, by leaching and cooling of the solution

摘要

A method for preparing a salt, particularly potassium chloride, by leaching a salt formation with an injected brine solution, and separating salts from the saturated solution by cooling said solution to the eutectic point temperature, recycling the hydrates and crystal mixtures, separating out the crystals, and reinjecting the remaining brine solution.
