A method for the production of langbeinite and potassium chloride by processing of kainite

摘要

Novel process for the processing of kainite (kcl × mgso₄ × 2,75 H₂O), which contain admixtures of kcl and nacl, kcl to langbeinite and potash fertilizer (). The inevitable occurrence of dissolved mgcl₂ in the final solution is only about a third as high as in the case of the currently used processes, so that the environmental pollution or the costs for the mgcl₂ Elimination can be reduced.
