METHOD FOR PROCESSING OF BERYLLIUM METAL WASTES

摘要

FIELD: sewage treatment facilities. ^ SUBSTANCE: invention may be used in production of fluoroberyllate ammonia - initial product for production of beryllium and its compounds. Method for processing of beryllium metal wastes includes operations of flushing from foreign admixtures, chopping to size of 2-5 mm and dilution in solution of ammonia bifluoride during heating. Process of beryllium metal wastes dilution is done in presence of oxidant - nitric acid or ammonia nitrate taken in amount of 0.4-0.8 mole per mole of metal powder, at the temperature of 85-90C. Ammonia bifluoride is taken in amount of 180-200% from stoichiometry. ^ EFFECT: invention makes it possible to reduce release of fire-and-explosive hazardous gaseous hydrogen and to prevent possible exhaust of highly toxic fluoride-beryllium pulp from reactor. ^ 1 tbl, 1 ex
