ABSTRACT:
A process of making a granulated MgO-containing potassium salt fertilizer containing potassium sulfate, and having a high abrasion resistance and high compression resistance, includes preparing a langbeinite slurry binder without an evaporation of a magnesium chloride-containing solution with heating at a temperature of from 95.degree. to 110.degree. C. with a density of from 1.6 to 1.7 g/cm.sup.3, mixing the potassium salt and recyclable fines with the langbeinite at a temperature of from 75.degree. to 100.degree. C., granulating in a granulating drum, screening to form the fertilizer and recyclable fines; and recovery and recycle of the fines. The liquid langbeinite binder can be made by mixing a mixture of magnesium sulfate and/or kieserite with potassium sulfate, schoenite and/or leonite the potassium sulfate and the magnesium sulfate being present in a mole ratio of from 1:1.5 through 1:3 and heating the mixture to a temperature of 95.degree. to 110.degree. C. with a turbidity density of 1.6 to 1.7 g/cm.sup.3.
