METHOD OF ISOLATION OF STRONTIUM NITRATE PRECIPITATE FROM NITRIC ACID EXTRACT Russian patent published in 1994 - IPC

Abstract RU 2024434 C1

FIELD: inorganic chemistry. SUBSTANCE: nitric acid extract is prepared at phosphate raw decomposition. Suspension is separated by settling at specific output 0,2-0,3 t/m2·h preparing the condensed precipitate and upper pouring. Then upper pouring is passed by ascending flow through the thin- layer modulus at specific output 1.5-2.5 1,5-2,5 m3/m·h. EFFECT: method ensures to decrease the loss of the end product. 1 tbl, 1 dwg
