Abstract
1. Способ разложения молибденитовых концентратов, включающий обработку исходного материала смесью азотной и серной кислот в присутствии кислорода в герметичных условиях, отличающийся тем, что, с целью создания экологически чистой технологии, упрощения процесса за счет проведения его при атмосферном давлении при сохранении высокой степени извлечения молибдена, обработку проводят при температуре, определяемой соотношением160 ≥ T = 167 - 501gC ≥ 30,где T - температура обработки исходного материала смесью азотной и серной кислот,C;C - концентрация азотной кислоты в смеси, г/л.2. Способ по п.1, отличающийся тем, что обработку проводят при 71 - 80C и концентрации азотной кислоты 20 - 50 г/л.1. The method of decomposition of molybdenite concentrates, including processing of the source material with a mixture of nitric and sulfuric acids in the presence of oxygen in sealed conditions, characterized in that, in order to create environmentally friendly technology, to simplify the process by conducting it at atmospheric pressure while maintaining a high degree of molybdenum , the treatment is carried out at a temperature determined by the ratio of 160 ≥ T = 167 - 501gC ≥ 30, where T is the temperature of processing the starting material with a mixture of nitric and sulfuric acids, C; C is the concentration of a zotic acid in the mixture, g / l.2. The method according to claim 1, characterized in that the treatment is carried out at 71 - 80C and a concentration of nitric acid of 20-50 g / l.
