Abstract

In this article the results of process for obtaining magnesium containing carbonate ammonium nitrate (CAN) by interaction of ammonium nitrate melt in dolomite mineral (DM) from “Shorsu”, Fergana region, have been given. Mass ratio of AN:DM is varied from 100 : 3 tо 100 : 35. The prilling method was used to granulate nitrate-carbonate melt. It was determined that the composition and property of fertilizer obtained. The possibility of granular fertilizer production with content of 25.49-32.77% of nitrogen, 0.90-8.09% СаО, 0.56-4.97% MgO and petty amount of potassium was shown. The main task for modification of AN is increasing strength of product. It was shown that if this strength for is 1.6 MPa for novel fertilizer with content AN:DM = 100 : 35 constitutes 10,18 МПа.
