Abstract
1.Способ извлечения урана из трудновскрываемых руд, заключающийся в их окислительном обжиге и сернокислотном выщелачивании металла из огарка, отличающийся тем, что обжигу при температуре 500-700°С подвергают дробленную руду крупностью - 2 или - 5 мм, полученный в результате обжига огарок измельчают и используют для нейтрализации содержащегося в отходящих газах диоксида серы, нейтрализованную пульпу выводят из скруббера и направляют на выщелачивание урана серной кислотой. ! 2. Способ по п.1, отличающийся тем, что уловленную в циклоне пыль гранулируют, и гранулы направляют на обжиг совместно с рудой.1. The method of extracting uranium from hard-to-open ores, which consists in their oxidative roasting and sulfuric acid leaching of metal from the cinder, characterized in that the crushed ore with a grain size of 2 or 5 mm is subjected to firing at a temperature of 500-700 ° C; and used to neutralize the sulfur dioxide contained in the exhaust gases, the neutralized pulp is removed from the scrubber and sent to the leaching of uranium with sulfuric acid. ! 2. The method according to claim 1, characterized in that the dust trapped in the cyclone is granulated, and the granules are sent for firing together with the ore.
