Water-soluble solid particles are transported through a pipeline as an oil slurry by (1) mixing 20-75% of the water-soluble solid particle with up to 5% of an aqueous solution, (2) slurring the mixture with oil, (3) transporting the slurry to a terminal through the pipeline, (4) introducing the slurry into a separator along with a saturated aqueous solution containing an electrolyte to cause phase transfer of the water-soluble particles from the oil to the aqueous phase, (5) separating the phases, and (6) recovering the water-soluble particles from the saturated aqueous phase. Specifically, sylvite (potassium chloride) is thus mixed with saturated brine before forming the oil slurry and at the terminal it is also mixed with saturated brine.
