Abstract
1. Способ выщелачивания урана из руд преимущественно для кучного или подземного выщелачивания, включающий предварительное приготовление выщелачивающего раствора с доукреплением его серной кислотой и вводом искусственного окислителя, фильтрацию выщелачивающего раствора через руду с переходом в него окисленных рудных минералов в виде ионов урана и двухвалентного и трехвалентного железа, перевод их в фильтрат, извлечение из последнего урана и получение маточного раствора, отличающийся тем, что после предварительного приготовления выщелачивающий раствор дополнительно обрабатывают кислородосодержащим агентом и корректируют окислительно-восстановительный потенциал выщелачивающего раствора путем поддержания соотношения концентраций ионов трехвалентного железа и двухвалентного железа не менее 0,5, причем кислородосодержащий агент вводят непосредственно в магистраль подачи в закачную скважину.2. Способ по п.1, отличающийся тем, что в качестве кислородосодержащего агента используют воздух и/или воздух, обогащенный кислородом, и/или технический кислород.3. Способ по п.1, отличающийся тем, что маточный раствор используют многократно для приготовления циркулирующего выщелачивающего раствора.1. The method of leaching uranium from ores mainly for heap or underground leaching, including the preliminary preparation of the leaching solution with the addition of sulfuric acid and the introduction of an artificial oxidizing agent, filtering the leaching solution through the ore with the passage of oxidized ore minerals into it in the form of uranium and divalent and ferric ions , transferring them to the filtrate, extracting from the last uranium and obtaining a mother liquor, characterized in that after preliminary preparation -paying solution was further treated with an oxygen agent and adjusting the redox potential of the leaching solution by maintaining the ratio of concentrations of ferric ions and bivalent iron was less than 0.5, wherein the oxygen containing agent is introduced directly into stored pressure in the delivery line skvazhinu.2. The method according to claim 1, characterized in that as the oxygen-containing agent use air and / or air enriched with oxygen, and / or technical oxygen. The method according to claim 1, characterized in that the mother liquor is used repeatedly to prepare a circulating leach solution.
