FIELD: chemistry.
SUBSTANCE: invention refers to the method for preparation of ammonium nitrate limestone used in agriculture. The essence of the method lies in that the conversion chalk with moisture less than 1 wt % is mixed with fusion cake or ammonium nitrate concentrated solution in the presence of inhibitor of calcium nitrate forming with following granulation of obtained suspension. The conversion chalk fed for mixing contains ammonium nitrate preferably in amounts of 1-3 wt %.
EFFECT: decrease of the general dust losses and chalk content in the dust and the simplification of the scrubber solutions disposal.
