METHOD FOR UTILIZATION OF MANGANESE

摘要

FIELD: chemical technology, applicable in processes involved in recovery of manganese from solutions and pulps containing uranium and its decay products. SUBSTANCE: solutions containing manganese and radioactive elements with pH 4.5 are alkalized with lime to pH 7.0. Solution is separated from sediments and manganese products are precipitated by carbonate salts of ammonium or alkali metals. EFFECT: reduced content of radioactive impurities in products of manganese utilization.
