FIELD: inorganic chemistry. SUBSTANCE: method involves mixing zinc oxide, water and solution of zinc monophosphate at weight ratio = 1:(1-4):(3-11), respectively, followed by addition of nitric acid and solution of calcium nitrate at amount 0.1-5.0 weight % (as measured for calcium). Temperature of reaction mixture is 50-60 C. Nitric acid is added at the rate 70-120 kg/min. The proposed concentrate is used in metallurgy and other industries. EFFECT: increased stability of concentrate, simplified method. 4 tbl
