Abstract
Process for the preparation of hydrated potassium magnesium sulfate, very pure, from natural minerals of potassium chloride-magnesium sulfate containing nacl, especially kinite, characterized in that the raw ore, preferably fine ground, is treated while stirring vigorously, with water used in an amount equal to, or slightly greater than, the amount necessary to dissolve the mgcl2 released by the treatment under equilibrium conditions in order to produce finely divided potassium magnesium sulfate, while the nacl is left virtually unchanged; the salt mixture is suspended in a separating liquid in which the sedimentation rate of nacl is greater than that of potassium-magnesium sulfate; and the latter is separated from the former by decantation or the like.
