Abstract: 
The technological and economic evaluation of two processes of langbeinite concentrate processing in a conditioned fertilizer was carried out with using mineral acids (nitric and phosphatic acid) for its dissolution. The first process allows to obtain non-chloride fertilizer (potassium-magnesium), and the second one allows to obtain not only potassium-magnesium, but such complex nitrogen-phosphorus fertilizer as diammophos. The optimal conditions for realization processes of acid dissolution, salting-out of schoenite from obtained acid-saline solutions using isopropyl alcohol, neutralization of solution phosphoric acid by ammonia were determined. It is shown that the obtained products entirely meet the requirements of standards. Technical and economic calculations confirmed the profitability and feasibility of the proposed technological processes.
